The transfer of electrons from the primary electron acceptor of photosystem II to the P700 chlorophyll a molecules of photosyste
sesenic [268]

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.

Which of the following is not an observation or inference on which natural selection is based?
olga2289 [7]

Answer: B. Poorly adapted individuals never produce offspring

Explanation:

Natural selection is a theory that states organisms adapts to its environment due to differences in their phenotypes. So, <u>individuals with favorable traits are more likely to survive and reproduce</u>. It is a key mechanism of evolution, which is the change in traits of a population over generations.

<u>Populations respond to natural selection if they contain heritable variation </u>among them, wich means that individuals differ in the traits they transmit to their offspring.

Because of the environmental selection pressures, individuals produce more offspring than their environment can support. <u>The pressure determines which individuals will survive and reproduce</u>, while others will die because of predation or diseases. So, natural selection is based on the observations of adapted individuals.
