Answer:

Genetic variation occurs.

Mutations are not copied over and over again.

Explanation:

Meiosis is a type of cell division that adds genetic variations in the progeny through the process of crossing over. These genetic variations impart a survival advantage to the population and prevent species extinction under unfavorable conditions. Since crossing over during meiosis produces new gene combinations, meiosis does not always allow transmission of mutation to the progeny. In this way, it helps to get rid of harmful mutations.

For each glucose that enters glycolysis, _____ nadh enter the electron transport chain.

SIZIF [17.4K]

The answer is 10 NADH.
For each glucose molecule that enters glycolysis, a total of 10 NADH are produced.
That is; during glycolysis 2 NADH are produced, while another two are produced in the conversion of pyruvic acid to acetyl-CoA, and in the Citric acid Cycle 6 NADH are produced, that makes a total of 10 NADH, which are then taken to the electron transport chain to produce ATP.
