Genetic drift is best described as the redistribution of the frequency of gene occurrence in a(n)
a. population
b. organism
c. ecosystem
d. disaster

The right answer is A. population.

Genetic drift is one of the mechanisms of evolution that leads to the creation of new species from populations of individuals. This mechanism is that of random variation of allelic frequencies within a population and over generations.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

explanation:

i didn't have the answer choices , but i tried my best.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
