ale4655 [162]

Answer:

The nuclei of the skin cells produced by mitosis will have identical genetic material as that of the parent cell.

It is because mitosis is a type of cell division in which a parent cell divides into two daughter cells, each having equal and identical chromosomes as that of the parent cell.

In addition, events like crossing over do not take place due to which no genetic variation is developed in the daughter cells.

The process of mitosis is mainly involved in the repair and growth of the body.

AlekseyPX

The right answer is Filtration.

An opportunistic predator switches prey, capturing whichever prey species is most abundant. As soon as the prey numbers dwindle
Sunny_sXe [5.5K]

Answer:

The correct answer is keystone predator.

Explanation:

In sustaining the composition of an ecological community, a keystone species plays an essential function. In the absence of keystone species, the ecosystem would fail to exist and would become drastically different. A predator is a classic illustration of a predator, which inhibits a specific herbivorous species from eradicating the dominant species of plants. In the non-existence of predators, the herbivorous prey would increase enormously and would clean the entire essential plant species, and thus, drastically change the significance of the ecosystem.
