Question

a student claims that dna determines the structures of pheromone - detecting proteins in bees. which evidence best supports the students claim? a bee cells contain both dna and pheromone - detecting proteins. b a single bee can only produce one pheromone - detecting protein. c bee dna contains unique genes for each pheromone - detecting protein. d the queen bee contains more dna than other bees that receive pheromone signals.

Explanation:

Genes in DNA code for proteins. If bee DNA has unique genes for each pheromone - detecting protein, it shows a direct link between DNA and the structure of these proteins. Option A just states that both are present but no causal link. Option B about the number of proteins a bee can produce doesn't address the DNA - protein structure relationship. Option D about the amount of DNA in queen bees compared to others is not relevant to how DNA determines protein structure.

Answer:

C. Bee DNA contains unique genes for each pheromone - detecting protein.
