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.

Unit 2This assignment consists of traveling to the sites listed above and writing a brief paragraph about your visit to that site, and then answering some questions after you have looked over the chapters in the text and in resources for Unit 2. http://www.cellsalive.com/toc.htm#microbiol2. Assume you are looking under the microscope at a Gram-stained slide of an open wound, and you see large red rod shaped cells, and smaller blue violet round cells. What is your explanation for the red and blue cells?3.

Assume you are looking under the microscope at a Gram-stained slide of an open wound, and you see large red rod shaped cells, and smaller blue violet round cells. What is your explanation for the red and blue cells?3. Explain the gram stain, and what does the gram stain tell you about the anatomical differences in cells? What information is gained from this staining technique, and how could that information affect an ill patient?Unit 3 chapter 3 and 5:•1. A facultative anaerobe utilizes glucose either by fermentation or by respiration. If more ATP is generated through respiration, why is the rate of glucose consumption less when the microbe uses respiration than when it uses fermentation? .2. What does a cell need to produce energy? •3. Explain how competitive and noncompetive inhibitors work. .•4. Define growth, and list the requirements for various organisms to “grow”. .•5. this is the question for the discussion board: Explain how a particular microbe responds to efforts to control its growth. (you may work with other students in this class to complete this part of the assignment, be sure to list the names of all involved in developing this activity when you post at discussion board).1. choose a microbe, 2. then research what environmental and O2 requirements are necessary for your microbe to grow. 3. What are the necessary growth factors for your particular microbe, and 4. how you could influence its ability to grow by this knowledge.
