Answer:
b. the bottleneck effect.
Explanation:
The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.
The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.
The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.
Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.
The photosystems are sets of chlorophyll molecules and other pigments and transmembrane proteins packed in the thylakoids, the transfer of electrons from the primary electron acceptor of photosystem II to the P700 chlorophyll a molecules of photosystem I is called photophosphorylation.
<h3>What is photophosphorylation?</h3>
It is the global process of transformation of the energy stored in the electron of the reactive center excited by light, in a pyrophosphate bond of an ADP molecule.
When a photon is absorbed by one of the pigments of photosystem II, it quickly bounces off the other molecules until it reaches chlorophyll a in the reaction center.
The electron, after leaving photosystem II, reaches the reaction center of photosystem I, where chlorophyll P700 is, the pigments absorb light and the electron reacquires a high level of energy.
Therefore, we can conclude that when this molecule absorbs light energy, an electron is thrown up to a higher energy level and transferred to another molecule, a primary electron acceptor.

The number of fossils found, the fact that fossils are oftentimes just a cast/mold of the organism with no real remains, and no interbreeding.
As time moves forward, we still strive towards better methods to answer questions about extinct organisms.
Answer:
Within a population, each individual mutation is extremely rare when it first occurs; often there is just one copy of it in the gene pool of an entire species. But huge numbers of mutations may occur every generation in the species as a whole.
