BIOLOGY HELP

Hey, I’m really having trouble with 2 questions in particular on my Biology homework and was wondering if someone could please help me out, or at least explain what I need to write to me. The two questions are:
1. In the original TV series of Star Trek, Mr. Spock reported the discovery of a possible life form based on element 14 (Silicon0 instead of element 6 (Carbon). As a Federation Science Officer station in San Francisco, you request the following information from the crew of the Enterprise:
a) Describe the characteristics of life needed to classify the entity as a potential life form.
b) Discuss how the atomic structure of silicon allows it to function like carbon.
c) Draw the general structure of an amino acid based on silicon (Si) instead of carbon.2. The physical structure of a protein often reflects and affects its function:
a) Describe THREE types of chemical bonds/interactions found in proteins. For each type, explain its role in determining protein structure.
b) Discuss how protein structure is likely to be affected if changes in the pH or salt content are made to the environment of the protein, or if the temperature is increased greatly.
c) Speculate on what might happen to the structure of a hydrophilic protein that is places into a hydrophobic environment. Explain.
d) A mutation has changed a non-polar amino acid in a protein to a polar amino acid. Discuss what affect this might have on the protein’s structure and function.

SECTION AStep 1: Write 3-4 sentences answering the following questions:Identify and describe a recent change occurring in your workplace. It could be a change in the levels of staffing, a change in policy, such as time off or tuition reimbursement, a change in use of equipment or supplies, a change in charting/computerized medical records, etc. Describe the change in 4 sentences. 1 of the sentences should address the rationale for the change. Step 2: Begin researching scholarly articles for the past five years related to the change issue identified in Step 1. Complete a 6 columns table of the references found including the following: Author Last name, First Initial (year)Title of article.Title Of Publication,Volume # (Issue #)pages of the article. Submit the Reference List Table to your instructor through the “course assignment area”. A minimum of (6) scholarly references are needed to complete this assignments- you may find more. SAMPLEChange Issue: Low census staffing policy.Currently, staff go home when the patient census is low based on tenure, so that the same staff are continually going home resulting in a lower paychecks for these nurses. The proposed change is to rotate all staff to leave when the census is low, regardless of tenure so the burden of potentially lower pay is shared among the entire staff, and not the same few.Author Last Name, First Initial.(Year).Title of Article.Title of Publication,Volume #(Issue #),Pages.1.

According to the Theory of Evolution, Natural Selection is the mechanism by which evolution occurs. Remember: evolution occurs at the level of the population. Individuals do not evolve, populations evolve.
The process of Natural selection is based on the following four postulates (listed in your textbook on page 288):
Postulate 1 – Individual members of a population differ from one another in many respects.
Postulate 2 – At least some of the differences among members of a population are due to characteristics that may be passed from parent to offspring. That is, they are heritable or genetic.
Postulate 3 – In each generation, some individuals in a population survive and reproduce successfully but others do not.
Postulate 4 – The fate of individuals is not determined by luck. Instead, an individual’s likelihood of survival and reproduction depends on its characteristics. Individuals with advantageous traits survive longest and leave the most offspring, a process known as Natural Selection.
Assignment: Choose ONE animal species. Your goal is to describe the way in which an evolutionary change might occur for a particular characteristic (trait) of that species as a result of natural selection. The characteristic could be something like coloration pattern, length of the limbs, or size of the teeth or beak, or any measurable trait that is inherited.
The organism you choose should be a real one but the evolutionary change you describe can be real or theoretical.
In your own words,
Explain how the change in this trait occurs in terms of the four postulates listed above and in the book. You will describe what the population starts out like at time zero and then what it will look like at a later time, as a result of natural selection.
Make sure to explain the process by which the changes occurred. What is the selective pressure? Explain why the change might confer more fitness to a particular environment?
Tips: Make sure to include the following in your…

Why is there radioactive Carbon in the starch?

BIOLOGY

A photosynthesis experiment uses Chlorella to track the route taken by 14C in photosynthesis. The 14C is provided from CO2 and no new sources of CO2 are available. After the experiment the scientist extracts all of the starch produced and analyses the Carbon present. She finds that only half of the carbon is 14C. She repeats the experiment with more time and twice as much CO2 and finds that three quarters of the Carbon in the starch is radioactive.
Answer the following questions about the experiment:
Why is there radioactive Carbon in the starch? 2 marks
Why is only some of the Carbon in starch radioactive after the experiment? 2 marks
Using ideas from the Calvin cycle explain why doubling the amount of radioactive Carbon does not lead to all of the Carbon in starch being radioactive. 5 marks
How did Calvin himself use radioactive carbon? 5 marks
i got a deadline please help me.
