Light absorbing pigment that are not at the reaction center of a photosystem increases the amount of the visible light spectrum that can be harnessed for photosynthesis (answer C). The chlorophyll is the reaction center. whereby light is absorbed by chlorophyll and molecules are bound to reaction center protein in the thylakoid membrane.
Answer:
Neural crest -
Explanation:
Neural crest -
The neural crest is those temporary sets of cells that are stick to particular vertebrates that arise due to the embryonic layer of germs. Neural crest provides a way to produce PNS(peripheral nervous system).
These cells are migratory cells that can develop into different cells tissue all over the body.
The shells of a certain species of marine snail are highly variable, with some snail shells being solid colors and others being striped. Which condition of natural selection is this most related to?
a) artificial variation
b) environmental variation
c) genetic variation
d) no variation
Answer:
c) genetic variation
Explanation:
The process of natural selection can operate on a population only when the population has genetic variations. This means that different variants of a genetic trait must be present in the population. In the species of marine snails, some snails have solid colored shells while the others have striped shells. Here, the snail population has genetic variations with respect to their shells. The natural selection would favor the shells which impart survival fitness to snails under the prevailing conditions.
