Answered by GPT-4o mini
The correct response is:

**proteins.**

Genes contain specific instructions for how to make proteins.
Answered by GPT-4o mini
The correct response is:

**not heritable changes in gene structure of a population.**

Epigenetic changes typically refer to modifications that affect gene expression without altering the underlying DNA sequence and are often not passed on to the next generation.
Answered by GPT-4o mini
The correct response is:

**gamete cells.**

Meiosis is the process that produces gametes, which are reproductive cells (sperm and eggs in animals).
Answered by GPT-4o mini
The correct response is:

**smoking tobacco.**

Exposure to harmful substances like tobacco can increase the likelihood of mutations in germ cells, which can then be passed on to offspring.
Answered by GPT-4o mini
The correct response is:

**can change DNA sequences.**

Epigenetics involves changes in gene expression without altering the underlying DNA sequence, while mutations involve actual changes to the DNA sequences themselves.
