question 9
2 pts
what level of protein structure is associated with the sequence of amino acids?
tertiary
secondary
primary
question 10
2 pts
which of the following elements is not particularly associated with living things?
nitrogen
oxygen
silicon

Explanation:

• For Question 9: The primary structure of a protein is the linear sequence of amino - acids. Secondary structure involves local folding like alpha - helices and beta - sheets, and tertiary structure is the overall 3 - D shape.
• For Question 10: Nitrogen and oxygen are essential for living things as they are part of many biological molecules such as proteins, nucleic acids, etc. Silicon is not as crucial for the fundamental biological processes in most living organisms.

Answer:

Question 9: C. primary
Question 10: C. silicon
