Analyze Question 3
This question asks for a shared function of lipids and carbohydrates in animal cells. Let's evaluate the options using our knowledge of Lipid Functions and Carbohydrate Functions:
- "provide insulation": While lipids (fats) provide thermal insulation, carbohydrates do not serve this function.
- "form cell walls": Animal cells do not have cell walls.
- "contain nitrogen": Neither typical lipids nor simple carbohydrates contain nitrogen (they are composed of carbon, hydrogen, and oxygen).
- "store energy": Both biomolecules are crucial for energy storage. Carbohydrates (like glycogen) provide short-term energy storage, while lipids (like triglycerides) provide long-term energy storage.
Analyze Question 4
This question asks for the building block of proteins. Let's evaluate the options using our knowledge of Protein Monomers:
- "fatty acids": These are components of lipids.
- "nucleotides": These are the monomers of nucleic acids (DNA and RNA).
- "monosaccharides (simple sugars)": These are the monomers of carbohydrates.
- "amino acids": These are the monomers that link together via peptide bonds to form proteins.
