Question

what controls traits and inheritance?
○ gametes
○ nucleic acids
○ proteins
○ temperature

Explanation:

To determine what controls traits and inheritance, we analyze each option:

• Gametes are sex cells (sperm/egg) involved in reproduction, not directly controlling traits/inheritance.
• Nucleic acids (like DNA) store genetic info that controls traits and inheritance via genes.
• Proteins are products of gene expression, not the controllers of inheritance.
• Temperature is an environmental factor, not a controller of traits/inheritance.

So nucleic acids are the correct choice.

Answer:

B. nucleic acids
