During exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This information is then sen

t to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism. Which statement is best demonstrated by this scenario? A. Hormones act as signal molecules between all body systems. B. Increased heart rate and blood flow decrease oxygen supply. C. Exercise is important for the body to function properly. D. Nerves transmit and respond to every major system in the body.

Certain cellular organelles use oxygen to release energy from glucose true or false
schepotkina [342]
That is completely accurate so your choice is TRUE. This process is known as cellular respiration where oxygen and glucose are its reactants. Oxygen and glucose both react in the cell when oxygen first enters it. Energy is later released as the glucose breaks down and creates new forms known as carbon dioxide and H2O (water). 

Let me know if you need further info.

Consider two very distantly related species, Species A and Species B. These species live in distinct but similar environments an
never [62]

Answer:

convergent evolution

Explanation:

If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.

why ?

size - very large compared to other planets

Its relative closeness (compared to other stars)

How many rounds of replication does it take for an incorporation error to be established as a base pair change?
iris [78.8K]

Answer:

Just one round without DNA repair

Explanation:

When an error occurs before or during replication, in a normal system, there is always proofreading and correction. If the error is not corrected during replication, it can then be corrected by the DNA damage repair system. But if not also corrected, the error becomes fixed and subsequent replication will produce this error
