I would say immigration only.
emigration would theoretically reduce the genetic variation as unique individuals leave, but immigration would bring unique traits into circulation in an ecosystem.
I'm not super great at biogy tho so this might not be right... :)
O do not receive enough oxygen during a strenuous exercise.
Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. ... ATP can provide energy for other processes such as muscle contractions.
Paraphrasing is the act of rewording, revising, simplifying and expressing the text in your own words with additional clarity. Note that condensing the text to a shorter form should not be in your interests because that would be summarizing, not paraphrasing. Check this out:

Being deceased means that life once inhabited the being and has left it. Just as a moose gains life from conception, it's deemed dead once life has left it. In science, nonliving organisms and lifeless organisms are not the same thing; one was gifted life and one was inanimate from the beginning.

Telomerase is involved in adding DNA to the end of the lagging strand.
At the ends of linear chromosomes (telomeres), telomerase uses its built-in RNA template to extend the parent DNA template near the end of the lagging strand, providing room for an RNA primer so that lagging strand synthesis can be completed to the end of the chromosome
