The answer is; graph A

Breathing increases during exercise because the body is demanding more oxygen for the muscles. The hypothalamus detects the increased carbon dioxide in the blood dur9ng exercise and its commands the lungs to breath faster and deeper. When exercise stops, the body is restored to resting through homeostasis.

The correct answer is: 3.A

During the exercise, heartbeat and breathing rates increase. The heart must increase its rate of pumping in order to deliver oxygen to the muscles faster. The demand for the oxygen increase, the lungs must work harder and the breathing rate increases. As a result, more carbon dioxide is produced and it needs to be removed.

Katen [24]
<h2>Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>

Explanation:

In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.

In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate  molecule that consists of two new strands.

In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.

He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.

PilotLPTM [1.2K]

Answer:The based on this information interaction between these two species can best be described as COMPETITION. Correct option is B

Explanation:

Competition occurs between two species that shares the same requirements ( especially food) for survival.

Both the Western Toad and the Bull Frog has a similar niche because they require the same type of food (beetles, bees, and small aquatic insects) to survive in the environment of Arroyo Seco. Only one of the species will coexist in that environment and it's usually the survival of the fittest.

This explains the competitive exclusion principle proposed by Georgii Gause in 1934.

The shiga and diphtheria toxin are proves to be harmful in the humans and causes harmful disease. Both these toxins inhibit the protein synthesis or translation of the host cell. The inhibition of protein synthesis causes drastic harmful effects in the individual.
