Im not SURE but i think its the endocrine system... i got a link that would help
Answer:
The answer however is yes you can, but you would probably die. The body mechanism for crying under water works just as fine above as below the water. So you can cry tears, they would just be mixed with the rest of the water.
Explanation:
Answer:
The correct answer is: As ventricular systole start, the AV valves are closed and the semilunar valves are closed. Because the ventricles are contracting and both valves are closed, pressure increases rapidly leading to ejection.
Explanation:
The heart functions like a bomb that pumps blood to every part of the body, which is fundamental for the proper function of every organ.
The cardiac cycle has two main phases: the diastole and the systole. During the diastole, blood returns from the body through the vena cava and is deposited in the right atrium of the heart. When the pressure in the right atrium becomes bigger than the pressure in the right ventricle, the tricuspid valve opens and the blood flows to the left atrium.
During systole, the atria suffer a depolarization that makes the atria's muscle contract. Thanks to this, the blood goes through the atria to the ventricles.
During isovolumetric contraction, the ventricles contract but the pulmonary and aortic valves remain closed. When the ventricular muscle contracts, the semilunar valves open.

The correct order of the following events on the mass flow of materials in the phloem is:
- Leaf cells produce sugar by photosynthesis.
- Solutes are actively transported into sieve tubes.
- Water diffuses into the sieve tubes.
- Sugar moves down the stem.
Correct answer: letter C.
This is because the mass flow of materials in the phloem must pass through all these processes in a consecutive and orderly manner, from the cell to the stem, in order to allow nutrients and other vital materials to reach from the plant roots to the leaves and fruits.
<h3>How is this transport of nutrients and other vital materials achieved?</h3>
This is accomplished by the transport of solutes through the phloem's network of channels, which contain fluids, mineral salts, vitamins and other nutrients essential to plant health. Mass flow also helps distribute oxygen and carbon dioxide to all parts of the plant. These materials are necessary for plant respiration and growth.
