Describe the characteristics of life needed to classify the entity as a potential life form.

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.
