Which is a requirement for natural selection to occur? heritable variations for some traitsthe ability of an organism to improve a trait during its lifetimeequal probability of survival for all offspringfewer offspring than the environment can support?

Answer;

heritable variations for some traits

Explanation;

-Natural selection is the process by which the organisms in a population that are best adapted to the environment increase in frequency relative to less well-adapted forms, over a number of generations.

Four general conditions necessary for natural selection to occur are:

-More organisms are born than can survive.

-Organisms vary in their characteristics, even within a species.

-Variation is inherited.

-Differences in reproduction and survival are due to variation among organisms.

If all four of these conditions occur, which they commonly do in both natural and human-influenced ecological systems, then natural selection will occur.

Insulin stimulates the liver to store glucose in the form of glycogen. A large fraction of glucose absorbed from the small intestine is immediately taken up by hepatocytes, which convert it into the storage polymer glycogen. Insulin has several effects in liver which stimulate glycogen synthesis.
