Secretes hormones that are stored in the posterior pituitary gland

Answers

Answer 1
Answer:

Answer:

Hypothalamus

Explanation:

The cell bodies of the neurosecretory cells of the paraventricular and the supraoptic nuclei of the hypothalamus synthesize the hormones oxytocin and antidiuretic hormone (ADH), also called vasopressin. These hormones are stored and released in blood by the posterior pituitary gland. The posterior pituitary does not synthesize hormones.

The hormones from the hypothalamus are packed into vesicles and are transported to the axon terminals of the posterior pituitary via the hypothalamic–hypophyseal tract. The hormones are stored in axon terminals and released in the blood when required.

Which of the following is not an example of homeostasis? a) After plunging into icy-cold water, Gary's core body temperature rapidly drops.
b)While exercising, Julia's heart rate and breathing increase to balance the increased oxygen use by her muscle cells.
c) On a hot day, to prevent dehydration, Martin’s kidneys remove very little water from his blood.
d)After eating a candy bar, April's pancreas secretes insulin, which removes the excess blood sugar.

Answers

The best answer to the question you have presented above is letter a. The statement that is NOT an example of homeostasis is 'After plunging into icy-cold water, Gary's core body temperature rapidly drops'. This is because it should increase rather than decrease. 

Answer:

a) After plunging into icy-cold water, Gary's core body temperature rapidly drops.

Explanation:

Homeostasis is the process by which our bodies find and reach equilibrium, could be physical or chemical, when you get into icy-cold water, for there to be homeostasis your body should get hotter in order to keep its normal temperature, but often the body tempereature just drops because there´s not much the vody can do against that.

When a virus invades the body, some B cells recognize it as nonself and produce plasma cells that release a substance to kill the virus. What is this substance called?

Answers

The correct answer is antibodies. When a virus invades the body, some anti-B antibodies cells recognize it as non-self and produce plasma cells that release a substance to kill the virus. That is why we have blood types figured out because it is important to know before any blood transfusion or transplantation, the antibodies of another person must also match with your, otherwise it's just going to be rejected by your body that might lead into some serious cases.

Assuming the stomata are open to the same degree, the rate of transpiration should _____ on a rainy day compared with a sunny day, because the relative size of the H2O concentration gradient from the inside to the outside of the leaf would _____.a) increase: increaseb) decline: decreasec) increase: decreased) decline: increasee) remain the same: not change

Answers

Answer:

decline: decrease

Explanation:

Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.

On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.

A fuel used in a nuclear power plant is _____.
uranium
coal
oil
gas

Answers

The fuel used in nuclear reactors is commonly uranium. Its unstable nature means that when it is hit with an electron it splits into two new atoms, one of which is Krypton. In the process of splitting large amounts of energy is released. This energy is used to heat water to produce steam, the steams rising energy is used to turn a turbine which produces the electric output of nuclear power stations.
