Answer:
The correct answer is D.) genetic drift
Explanation:
Genetic drift refers to a population's unpredictable oscillations in the number of gene variants. When the occurrence of various forms of a gene, known as alleles, increases and decreases by chance over time, this is known as genetic drift. The changes in allele frequencies are used to measure these differences in allele presence. I hope this helps! ^-^
Answer:
D. oxygen is the final electron acceptor.
Explanation:
Oxygen serves as the final electron acceptor in aerobic cellular respiration. The whole pathway includes glycolysis, Kreb's cycle, and oxidative phosphorylation.
Oxidation of NADH and FADH2 formed during glycolysis and Kreb's cycle through electron transport chain during oxidative phosphorylation includes molecular oxygen as the terminal electron acceptor.
The proton motive force generated during the electron transfer from NADH and FADH2 to oxygen gas drives phosphorylation of a large number of ADPs into ATPs.
Yes because movement is a characteristic of living things, and it is something that a living being must do to survive. For example, (at a cellular level) you need movement for growth, reproduction, and responses to stimuli.
