5 multiple choice 2 points which of the following would be a protein? oils hormone rna starch 6 multiple choice 2 points what are the characteristics of unsaturated fatty acids? liquid at room temperature, found in animal fats solid at room temperature, found in plant oils solid at room temperature, found in animal fats liquid at room temperature, found in plant oils 7 multiple choice 2 points what are the two main types of secondary structures in proteins? alpha helix and beta pleated sheet quartenary and tertiary structures primary and tertiary structures alpha helix and quaternary structure

Explanation:

• For question 5: Oils are lipids, RNA is a nucleic - acid, starch is a carbohydrate. Some hormones are proteins.
• For question 6: Unsaturated fatty acids are liquid at room temperature and are commonly found in plant oils. Saturated fatty acids in animal fats are solid at room temperature.
• For question 7: The two main types of secondary structures in proteins are the alpha - helix and the beta - pleated sheet.

Answer:

1. hormone
2. Liquid at room temperature, found in plant oils
3. Alpha helix and beta pleated sheet
