Investigation of Photosynthetic Pigments in Spinach Essay Example

Investigation of Photosynthetic Pigments in Spinach Paper Investigation of Photosynthetic Pigments in Spinach Michael Yacoub BIOL211 Lori Hayes Introduction: Purpose: To demonstrate the existence of the pigments of photosynthesis in spinach by separating them using chromatography, then measure them using spectrometry. There are multiple pigments in photosynthesis, the varying pigments allow the plant to absorb light at various wavelengths which allows the plant to derive energy from photons from most, if not all, light available in that region it grows in.

Chlorophylls are any of the few green pigments associated with certain bacterial membranes that are responsible for trapping light for energy in photosynthesis. Carotenes can be red, orange, or yellow lipid pigments and is often found as an accessory pigment in photosynthesis. Xanthophylls are yellow or orange pigment also usually found as an accessory pigment in photosynthesis. Although, these are not quite clear in the drawing shown below because they were hard to find in the provided samples, one can find these various pigments are found within the hloroplasts and more specifically within the thylakoid membrane within photosystems one and two. When testing to see what wavelengths are involved in the process of photosynthesis an action spectra was created; this is a graph that graphs the biological processes versus light wavelengths. An absorption spectrum however, is a graph of light absorption versus wavelength of light and allows one to see how much light is absorbed at each wavelength. This can also help show which pigments are present in the plant. In this lab an absorption spectra was created in order to elp identify the varying pigments present in the spinach leaf. Spectrophotometry at a specified wavelength. This experiment was testing the hypothesis that the wavelength shown through the pigment in solution will affect the amount of light absorbed by the solution. In specific, it was predicted that the darker the solution the greater the absorbance. Furthermore, various pigments will have higher absorbance values at specific wavelengths than other pigments at other wavelengths. There are two independent variables; the wavelengths of light shown through the pigments in olution, a quantitative variable, and the pigments in solution, a qualitative variable. There is only one dependent variable however and it is the absorbency measured, also a quantitative variable. Leaf Cross-section: Experiment: The procedure in the Biology 211: Majors Cellular Laboratory Manual was used as reference in the experiment. The experiment began with obtaining a piece of chromatography paper cut with 12 cm x 14 cm dimensions. Then a line 1. 5 cm from the bottom was made by rolling a penny over a spinach leaf, producing a 14 cm long green spinach line. Then, the chromatography paper was rolled into a cylinder and stapled to hold together; the line made by the spinach leaf was on the outside. Meanwhile, 20 mL of separation solvent was placed in a 600 mL beaker and the cylindrical chromatography paper was placed in it without having the solvent touch the green line and covered with plastic wrap. This set up was left alone to sit, vented by lifting up a corner of the plastic wrap, resealed and allowed to sit until the solvent line was approximately 1 cm from the end of the paper. Once the solvent line was bout 1 cm from the end of the paper it was removed from the solvent and allowed to dry. Then each section of pigment was cut as without including any other pigment. The instructor pooled all of the classes pigments and placed them in 80% acetone in separate beakers and sealed until all the color was eluted from the paper. One pigment in solution was given to individual lab groups and one group was given a solution that included all the pigments (pigment 5). Each group used spectrophotometry to measure the absorbance of each pigment starting with a avelength of 400 nm all the way to a wavelength of 710 nm with 10 nm increments; the 80% acetone was used as a blank and the machine was blanked every time the wavelength was changed. The absorbencies were recorded, the data was pooled and absorption spectrum was created. Our group was analyzing pigment E. Results: Figure 1 and Table 2 provide the collected chromatography data, the qualitative data was collected here. Table 1, Figure 2, and Figure 3 provide the spectrometry data. The quantitative data was collected here. Table: Shows conclusive evidence of peaks for pigment absorbance. Also the absorbance from the spinach leaf was included. Chromatography of Spinach Pigment # Pigment Color Distance Moved (mm) Rf Value Dark Green 11 0. 169 2 Light Green 28 0. 431 3 Light Yellow 0 0. 769 4 Dark Yellow 65 1. 00 Table: Shows different color of pigments as well as relative polarities in relation to the separation solvent. Figure : Shows the absorbance of Just the spinach leaf. Provides a comparison to pigments. Figure: Shows the relative peaks of absorbance for each pigment given the varying wavelength. Discussion: The hypothesis was proven to be correct, it was clear that different pigments were in the spinach leaf and each of those pigments was absorbing more light at specific wavelengths while having very low to no absorbance at other wavelengths- this can e seen in Figure 3, as well as Table 1. This is what helps the plant make use of as much light as possible in photosynthesis and not let anything go to waste. Pigments A, B, and C have two peaks while pigments D and E have only one peak in about the exact same spot. Something one can notice about the absorbance of the spinach leaf is that there is a range of wavelengths where there is very low absorbance. This definitely supported the proposed hypothesis because different pigments did have extremes, clearly showing that different pigments were better suited for varying wavelengths. The absorbances were so low at points because the pigments, Chlorophyll A, Chlorophyll B, Xanthophyll, and Carotene absorb the most light at different optimal wavelengths, so the absorbance would be low at times because it at a wavelength where the pigment would absorb the most light. Furthermore, this supports the hypothesis more simply because, in fact, the wavelength did affect the absorbance. Lastly, the darker solutions in fact did have higher absorbency peaks. This makes sense because Figure 2 models the spectra of Pigment A,B, and C in Figure 3. These pigments were the darker color which means they were most bundant in the spinach leaf. Therefore since these graphs model each other it would conclude that these were the major pigments. This also goes to define the concentrations of the pigments found in spinach. Pigment B since it closely modeled the spectra for Just spinach found in Figure 2, must be the major pigment component in spinach due to the fact that spinach is a combination of all the pigments that were isolated. Error that could be found in this lab probably is from misusage of the Spec-20. Mistakes such as not completely zeroing the machine occurred; this could esult in errors in the absorbance data. This could be fixed by getting better lab equipment. References: Biology 211 Majors Cellular Laboratory Manual Self Assessment: 1. I chose to use scatter-line plots. I chose this because I felt like it easily showed the peaks that I kept talking about. Also it showed the relation between the spinach and pigment absorption spectra well. 2. They are excellent. They have titles, the axes are labeled, and that have citations. 3. Excellent. I feel like I learned all the objectives for the lab, and I was able to effectively display the information.

SAT Sections, Sample Questions and Strategies

SAT Sections, Sample Questions and Strategies The SAT consists of four required sections: Reading, Writing and Language, Math (No Calculator), Math (Calculator). There is also an optional fifth section: the essay. The Reading section and the Writing and Language section are combined to calculate your Evidence-Based Reading/Writing score. The two math sections are combined to calculate your total Math score. Before taking the test, familiarize yourself with the types of questions and time limits of each section of the SAT. This familiarity will help you feel confident and prepared on test day. SAT Reading Test The SAT Reading Test comes first, and all questions are based on passages that youll read. Youll spend over an hour on this section. Number of Questions: 52Question Type: Multiple choice based on passagesTime: 65 minutes The Reading Test measures your ability to read carefully, compare passages, understand how an author constructs an argument, and figure out what words mean from their context. Realize that this is not an English test- passages will come from not just literature, but also U.S. or world history, the social sciences, and the sciences. The Reading Test may also include info-graphics, graphs, and tables, although you will not need to use math skills to analyze these elements of the test. Sample Questions These sample questions refer to a specific passage. 1. As used in line 32, horrid most nearly meansA) shocking.B) unpleasant.C) extremely bad.D) obnoxious. 2. What statement best characterizes the relationship between Dr. McAllister and Jane Lewis?A) Dr. McAllister admires Janes honesty.B) Dr. McAllister pities Jane because of her low social status.C) Dr. McAllister feels self conscious around Jane because she makes him aware of his failures.D) Dr. McAllister is disgusted by Janes lack of education and poor hygiene. In general, the skills required for the Reading Test are those youve been learning at school and not ones you can cram in preparation for the exam. If you are good at reading a text closely and carefully, you should do well on this section. That said, you should definitely take practice tests to figure out how carefully you need to read the passages and what pace you need to set to ensure you finish in time. For many students, the Reading Test is the most challenging section when it comes to time management. SAT Writing and Language Test The Writing and Language Test also consists of questions based on passages, but the types of questions are different from those on the Reading Test. In addition, the passages are generally shorter, and youll have less time to complete the section. Number of Questions: 44Type of Questions: Multiple choice based on passagesTime: 35 minutes Like the Reading Test, some questions in the Writing and Language Test will include graphs, info-graphics, tables, and charts, but you wont need to use your math skills to arrive at an answer. Questions can ask you about the best word choice for a given context, proper grammar and word usage, organizational elements of a passage, and the best methods for presenting evidence and making an argument. In the reading test, youll be provided a passage that has sentences and locations within the text marked by numbers. Sample Questions These sample questions refer to a specific passage. Which choice makes the most effective transition between the first and second paragraph?A) NO CHANGEB) Despite these dangers,C) Because of this evidence,D) Though the action would be unpopular, To make the ideas in the passage flow logically, sentence 4 should be locatedA) where it is now.B) after sentence 1.C) after sentence 4.D) after sentence 6. Familiarize yourself with this section by taking practice tests (like those from Khan Academy and the College Board). Another way to improve your score is to brush up on grammar rules. Be sure to study conjunction, commas, colon, and semi-colon usage as well as the rules for using commonly confused words, like its vs. its and that vs. which. The score from this section is combined with the score from the Reading Test to arrive at the Evidence-Based Reading and Writing score for the exam. SAT Math Exam The SAT Math Exam is comprised of two sections: SAT Math Test- No Calculator Number of Questions: 20Type of Questions: 15 multiple choice; 5 grid-inTime: 25 minutes SAT Math Test- Calculator Number of Questions: 38Type of Questions: 30 multiple choice; 8 grid-inTime: 55 minutes The results from the calculator and no calculator sections are combined to arrive at your SAT math score. The SAT Math Exam does not cover calculus. Youll need to know algebra and how to work with linear equations and systems. Youll also need to be able to interpret data represented in graphical forms, work with polynomial expressions, solve quadratic equations, and use function notation. Some questions will draw on geometry and trigonometry. Sample Questions 5x x - 2x 3 10 2x x -4In the equation above, what is the value of x?A) 3/4B) 3C) -2/5D) -3 For the following question, you may use a calculator. Grid your answer into the answer sheet.During rush hour traffic, Janet took 34 minutes to complete her 8 mile drive to work. What was her average speed during her drive. Round your answer to the nearest tenth of a mile per hour. Chances are, youre better in some areas of math than others. Use the free math practice materials at Khan Academy to identify your strengths and weaknesses. Then, rather than taking entire practice math tests, you can focus on the areas you find most difficult. SAT Essay (Optional) Most colleges and universities do not require the SAT Essay, but many schools recommend it. To write the essay, youll need to sign up and pay an additional fee when you register for the SAT. You will write the SAT Essay after all students have completed the Reading, Writing and Language, and Math Tests. You will have 50 minutes to write the essay. For the essay portion of the exam, you will be asked to read a passage, and then write an essay that responds to the following prompt. The passage changes for each exam, but the prompt is always the same: Write an essay in which you explain how [the author] builds an argument to persuade [his/her] audience that [author’s claim]. In your essay, analyze how [the author] uses one or more of the features listed above (or features of your own choice) to strengthen the logic and persuasiveness of [his/her] argument. Be sure that your analysis focuses on the most relevant features of the passage. Your essay should not explain whether you agree with [the author’s] claims, but rather explain how the author builds an argument to persuade [his/her] audience. Your SAT Essay will be read and scored by two different people who will assign scores of 1 to 4 in three areas: reading, analysis, and writing. The two scores from each area are then added together to create three scores ranging from 2 to 8. To prepare for the SAT Essay, be sure to look over the sample essays on the College Board website. Youll also find some good sample essays and essay strategies at Khan Academy.

Make up - Essay Example Moreover, the plan requires all businesses and workers to abide by these rules. For a long time Republican and Democratic presidents used legal authority in dealing with the issue. However, President Obama took a commonsense approach. The approach by the President relies on his executive authority to ensure everyone is accountable and capable of following the law in contributing to the US. The president took the approach as the country anticipates for the Congress and Republicans to act. No hindrances exist that can affect the president’s decision since US constitution as well as Immigration and Naturalization Act offer the Executive authority to come up with enforcement priorities that improve the way agencies apply the law. US Supreme Court agrees on this. The executive authority allows both Democrat and Republican presidents to act on immigration. All presidents after President Eisenhower have legal authority that enables them to deal with immigration (The White House). For a long time, the US immigration system has been broken making it pointlessly difficult for the country to draw the best talent around the globe. Skilled workers usually wait for years or even decades before obtaining green cards to allow them contribute fully to the country’s economy and gain citizenship with time. Entrepreneurs lack devoted immigration corridor to allow them develop their enterprises and create jobs in the country. Every year, the country’s universities educate a number of well talented students only to coerce them to return to their country of origin and compete against the US. Through the executive action by the President, the immigration system is set to enhance immigration of highly skilled workers, entrepreneurs, and graduates (The White House). In the past, skilled immigrants got temporary work visas. Only in cases where no American employees available to

Housing law Essay Example | Topics and Well Written Essays - 3000 words

Housing law - Essay Example Tackling both anti-social behavior and the causes of it has become a priority for the Government, Housing Corporation, RSL, and Local Authorities. Communities are demanding more effective ways to deal with this disease. "The Housing Corporation in its publication, "Themes from Inspection - Anti-Social Behavior" (June 2003) states: "Potential perpetrators must understand the consequences of anti-social behavior including the possible loss of their home, and realize that the association will take a tough line on unacceptable conduct". Property developers therefore have developed effective policies and procedures for tackling antisocial behavior in the areas in which it operates and we will work in partnership with residents and relevant agencies to ensure, as far as possible, that residents take responsibility for their actions and behave in a way which does not harass or intimidate others". "Anti-social behavior can have different meaning for different people. ... ose numerous unemployed junkie people begging by cash points, abandoned cars, litter and graffiti, young people using air guns to threaten and intimidate or people using fireworks as weapons", said David Blunkett, Home Secretary, in March 2003.

State Sovereignty Being Transformed By Globalisation Politics Essay

State Sovereignty Being Transformed By Globalisation Politics Essay The notion of state sovereignty in todays world cannot hold its ability as a result of globalisation. The Sovereign states in the previous years known, globalisation has successfully eroded that idea. The main impact of globalisation can be seen in the changing approaches of sovereign states when dealing with global changes. There are many factors that are made by globalisation which are known to be breaking up the sovereign state some factors such as the push for protection of human rights and also the influences of non-government organisations. The global push to bring out the universal agreement to human rights that was conducted after the world war two had seen the creation of the United Nations carter and the establishment of non-government organisations, which in the end signified the erosion of state sovereignty. Haass (2006) looks at sovereignty and globalisation and he argues that the United Carter is based on a contradiction, which tries to encourage the rights and movement towards self determination and individuals and groups and at the same time supports state sovereignty and territory. In effect the movement towards human rights and equality weakens the influence of sovereign states in order to allow individual rights throughout every state. Haass (2006) also claims that the making of Non-government organisations that was created to promote human rights for example Amnesty International has influence on limiting that actions of the state in various ways. By having the support of Non-government organisations this allows the United State to interpret Human Rights Charter in result to support individuals rather than upholding the state sovereignty. Through this we are able to see that the globalisation of Human Rights that is fuelled by the influence of NGOs has significant effect on the concept state sovereignty. Agnew (2009) has a look at globalisation and sovereignty and he suggest that globalisation does not provide protections for the state but it increases the ease of movement across nations. The ease of goods, diseases, cultures, drugs, and weapons that travel across borders show that the end of sovereign states is necessary to deal with the consequence of globalisation. The influence of the World Trade Organisation also suggests the transformation of state sovereignty as a result of globalisation. Governments must meet with the regulations that are set out by the WTO in order to maintain alliance and benefits on an international trading spectrum. Sassen (1996) looks at how the state is losing control and sovereignty in an age of globalisation. He says that in order for states to maintain defence and protection for themselves the sovereignty must be weakened. States are also reasserting power due to the effects of GFC by globalisation. The global economy is in rapid decline with GFC. It is shown that globalisation in the contemporary world has had great impact on the foundations of state sovereignty. State are not able to deal with international issues anymore without considering diverse factors which have appeared through the current globalised world. References: Agnew.A.J, 2009, Globalization and Sovereignty, Rowman Littlefield Publishers Inc, America. Haass.N.R, 2006, Sovereignty and Globalisation, the council on foreign relations, America. Sassen.S, 1996, losing control? Sovereignty in an age of globalization, Columbia University Press, America. Question Nine: How is global politics affected by culture and Nationalism? Culture and nationalism allows nations and individuals that are alike to stand together under similar ideologies, beliefs, customs and social norms. Nationalism also allows particular nation states to succeed for self-determination based on their history. On the other hand culture and nationalism are also significant in global conflict due to the overall rations between nations. Throughout history the effect of culture and nationalism on global politics can be traced. An important example of the effects of strong cultural identity and nationalistic pride is shown through the occurrence of World War One. Calhoun (2006) looks at Nationalism in the new world and points out that nationalism is an upcoming problem in global politics. The attempt to keep cultural ideals, nationalism is seen as the reason why there is growing conflicts in the contemporary world. Calhoun also points out that certainly ethnic conflicts and war are worsened by the mentioned ideologies. Nationalism and culture have shown to play a significant role in producing domestic policies such as tax, illegal immigrants, power and also relations between nations. The development of the state power has been strongly shown to be motivated by nationalistic and cultural beliefs on both domestic and international fields. Smith (2003) looks at the relationship between kinship and ethnicity and also nationalism as a key notion in modern day politics and decision making. The concept that Smith puts forward is further supported by Calhoun (2006), in the idea that national boundaries and identities are important to understand the contemporary world. Nationalism and cultural identity are applied by the world leaders and government policy makers to influence and approve decision making. Territorial claims of nation states by world leaders such as Palestinians, Israelis and Eritrea can be seen to use nationalism as justification for their actions. There are many problems seen in some states when small national groups have the feeling that they are not shown or their civil rights are not contained by the state for example the Kurds and Tibetans they seek for their own state which is refused to be accepted by their dominant state. In the twenty first century it is believed that Muslim countries will continue to change and it is shown that there are already a different variety of political, economical, social differences shown between some Muslim states for example the more wealthy countries such as Dubai have developed. References: Barnett.T.P.M, 2009, Great Powers: America and the World after Bush, G.P.Putnams Sons, America. Question Two: What were the key developments of the post-cold war era? The post cold war era saw a great change in the spread of ideologies as well as changes to governance of great world powers. Since the Cold-war era there has been additional unsteadiness that has formed in developing countries for example Asia, and also the Islamic terrorism and the US-led war on terror which involved Afghanistan and Iraq. The end of the cold was a very big historical turning point as measured by changes in the international system, the nation state and the international organizations. The Term cold car is referred to as the period of the US which changed over the period of 1945-89. The end of the cold war saw the creation of the United States as the single great world power. America had become the superpower of the world, this allowed for the spread of democracy across the western world. This resulted in the wide spread of capitalism and with an increase in economic growth. However, into the twenty first century changes to the power of America have occurred. Barnett (2009) indicates that there are emerging states of great powers across the globe this may include China, Japan or even Brazil. He points out that Chinas vast growing population as well as its great influence on trade, is a great challenge to America as a great power and recognises the USAs powers significant end. The GFC had also been seen as a big crisis for the US economy because it was moving up the level of unemployment. The fall of the Berlin Wall was also seen to be significant. The Berlin Wall divided Germany from its capital city, and it was knocked down because Germany was separated from political views so they knocked down the Berlin wall to make Germany one. There has also been the formation of the European Union (EU). In 1990s poverty remained a reality for the majority of people, the end of the cold war produced contradictory results in the less developed countries.

This document should be placed as an attachment to your discussion response. To include the document as an attachment, locate the attachment feature in the bottom left-hand corner of the discussion response box. In your response: †¢Describe which of these dispositions (as well as those noted in Chapter 10) you already exhibit on a regular basis. When working with toddlers myself and my co-worker use several of these dispositions listed in Chapter 10. For instance †¢Based on the discussion of career options in Chapter 10, identify at least two possible careers that interest you and that are a â€Å"good fit† based on your personal disposition reflection. Explain why you would be a good fit for both of your chosen careers. †¢Discuss which dispositions are still emerging for you and how will you plan to develop them for both of your possible future career choices. Guided Response: Review several of your classmates’ posts and respond to at least two of your peers. In your responses, suggest some further ways your peers can develop their emerging dispositions.

Personal Learning Insight 2. 1: My Dispositions Figure 2. 1: My dispositionstarget Individuals in the midst of becomingteachers should develop self-awareness oftheir own dispositions. After reading through the list of dispositions associated with effective teachers, pause a fewmoments to consider your own traits. Which of these dispositions are already evident in your demeanor? Do you believe these characteristics are part of who you are by virtue of birth or of experience? Are some dispositions still emerging, or needing to emerge? Because of the strong connection between dispositions and teaching styles, it is desirable forindividuals in the midst of becoming teachers to reflect and develop self-awareness of their owndispositions (Wadlington & Wadlington, 2011). As you complete this course and continue withother education courses, think about targeting some of the desirable dispositions as goals for yourongoing professional development. Use the My Dispositions Target (Figure 2. 1) to record yourinitial analysis of your dispositions. Many factors, other than desirable dispositions, are associated with learning how to successfully teach young children. The general public’sbelief that no specialized training is necessary to work with young children is simply a misconception. Research data has supported the positionthat teachers with specialized training and education in early childhood education is one of the more important factors in determining programquality for young children (NAECTE, 2008). Experts in the field of early childhood education rely on professional organizations for leadership indetermining what novice early childhood teachers should know (knowledge) and be able to do (skills).
