Coiling of shells can vary for snails. snails that coil to the left cannot mate with snails that coil to the right. this difference leads to reproductive isolation. what kind of reproductive isolation does this example indicate? mechanical isolation postzygotic isolation gametic isolation behavioral isolation

Its mechanical isolation. i checked on plato

Mechanical isolation

Explanation:

Mechanical isolation occurs when the reproductive structures of organism are not compatible. In this example, the coiling on the shells do not match, therefore the snails cannot reproduce.

Postzygotic isolation occurs when organisms have already fertilized an egg, but the offspring either died or was sterile.

Gametic isolation is when the gametes (egg cells and sperm cells) of organisms cannot produce offspring.

Behavioral isolation is a difference in reproductive behaviors such as mating calls that results in two organisms to refrain from reproducing with each other.

None of these apply except mechanical isolation.

stridor can't collapse a lung.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
