3) genetic mutations pass to offspring in gametes because gametes

Because gametes are the cells responsible for carrying the genetic characteristics that will be passed on from parents to children.

Explanation:

Gametes are the sex cells generated during sexual reproduction. There are male gametes that are called sperm (animals) or anterozoids (plants) and female, called eggs (animals) or oospheres (plants).

These cells are responsible for transmitting the genetic characteristics that will be passed on from parents to children, for this reason, we can say that genetic mutations pass to offspring through gametes.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
