Pz a rapid appearance of many new species of organism’s

happens just before an extinction event

leads to an increase in glaciation

is directly related to a drop in sea level

happens after a mass extinction

The correct option is D) happens after a mass extinction

Explanation:

A mass extinction can be described as an increase in the extinction of a certain kind of species from the world leaving only a few of the species behind with low genetic diversity.

After the mass extinction of a species, there is enough room for new species to inhabit the land. Hence, whenever a mass extinction occurs, it usually is accompanied by the rapid appearance of many new species which begin to colonize the land.

happens after a mass extinction

Explanation:

When a mass extinction occurs, a large number of living beings are decimated. This results in a large number of biological niches that are left without inhabitants, empty, or practically empty. Some living things manage to survive a situation of mass extinction. These beings occupy the niches used by those who died and are able to reproduce at a higher speed, since competition is less. These living beings are then able to reproduce a populous offspring that causes the appearance of many new species of organisms. This is because the organisms that survived the mass extinction have a characteristic favorable to their existence that will be passed on to their descendants.

ysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. lysosomal enzymes are synthesized in the endoplasmic reticulum (er), are transported to the golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.
