Answer:

B) habitat change

Explanation:

Habitat destruction (along with hunting and fishing) stands out among the factors that trigger biodiversity depletion. Usually this process occurs as a result of urbanization and deforestation to increase agricultural areas and development of major works. In addition, this destruction is also caused by global warming.

As their habitat is destroyed, many species are often forced to migrate to other areas, facing dangers and uncertainty of survival. Those species that are unable to find another place to settle, such as plants, have their population reduced or even often extinct.

A receptor can directly open a channel and thereby exert a(n) ____ effect, or it can produce slower but longer ____ effects.​
svlad2 [7]

Answer: ​ionotropic; metabotropic

Explanation:

A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.

Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.

The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
