The homeostatic is the ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium. The receptor, integrating center/control center, and effector are the three interdependent components of its control mechanism. In a homeostatic mechanism that involves the regulation of blood pressure, the brain serves as the integrating/control center that signals the kidney which is the effector to retain water if blood pressure is too low.

Who is most in danger from the effects of overfishing ?

faltersainse [42]

I don't think we can answer this question just like that. The question should be formulated a bit differently:

WHAT is in danger from the effects of overfishing?

Well, in the end of the "effect-spectrum" we are in danger, since we also eat fish. But the most affected species are the ones that form the aquatic ecosystems. Such as fish. Examples:

1 - Many of the fish we eat, feed on sea-weed. If there aren't enough fish to eat the growing population of sea-weed, many fish die of intoxication.

2 - We don't have almost any fish restrictions in a way, because we can eat basically all of them. Therefore, many fish (which are also being eaten) find themselves in a lack of food.

3 - Many times, we concentrate on a specific species, which is a main cause of the extinction of species.

Hope it helped,

What is the best example of how the nervous system maintains homeostasis?

Blizzard [7]

I'm not sure if it's the "best" example but.

If your blood tempature is low, the hypothalamus will issues reflex commands that make your body shiver. If you are hot, you will sweat is the opposite of this.

Another example is, if your blood contains pyrokines then you might have an infection so you begin to run a fever as your body's way to kill the pathogen at the direction of the hypothalamus.

Hope these examples help!

We breathe more quickly and deeply when we exercise. Why does this make sense? Select all that apply. a) Because when we exercis

storchak [24]

Answer:

a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.

c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.

d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.

Explanation:

During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.
