The _________ channels the waste-filled blood to the excretory system.a. Small intestine
b. Renal Artery
c. Ureter

Answers

It is the Renal Artery that channels the is waste-filled blood the excretory system. Main function of renal artery is to carry blood from the heart to the kidney. It starts from the heart and carries a volume of blood to the kidney to be filtered.

The main organs of the excretory system are the kidneys. Waste-filled blood is routed to the kidneys via the renal artery. The kidneys then filter the blood, removing excess water, salts, uric acid, and chemicals from medications or poisonous substances.

The genetic material contained in the nucleus of each of the new cells is most likely?

Answers

The answer is identical to the original body cell or it is half of the original body cell.

A cell cannot live forever so they either divide into two new cells through mitosis or die.In the process of mitosis one cell divides into two identical cells. So, a genetic material in the nucleus of each of the new cells will be identical to the original body cell.
Beside mitosis, there is meiosis. It is a cell division that results in the reduction of chromosome number by half. In this case, new cells will be haploid and there will be half less genetic material than it the original body cell.

Which of the following best explains how a biotic factor can control the population of a species in an ecosystem?A sudden drop in temperature may cause many individuals in a population to die.

Competition between two species may force one of them to migrate to survive.

Disease may lead to a decline in the reproductive rate of the species’ main predator.

Lack of water during a drought may cause many of the individuals in a population to die.

Answers

Answer:

The most appropriate answer would be Competition between two species may force one of them to migrate to survive.

Competition is a type of biological interaction in which organisms of same or different species compete for similar resources essential for their survival in an ecosystem.

Organisms can compete for limiting sources (such as air, water, food), territory, and mating rights.

In inter-species competition, species with the slightest advantage will grow and result in the migration or extinction of other species in that ecosystem.

Thus, the population of other species would decrease or extinct in that ecosystem.

For example, lion and cheetah may compete for their common prey that is, deer.

Answer:

B): Competition between two species may force one of them to migrate to survive.
