Answer:
The Cardiovascular System
Explanation:
The respiratory system draws air into the lungs. Oxygen diffuses through the walls of the alveoli and across the walls of the capillaries where it enteres the bloodstream. The oxygen molecules are picked up by red blood cells, which are pumped through the blood vessels by the action of the heart. As the red blood cells carrying oxygen pass through capillaries near the cells, oxygen diffuses into the cells.
An increase in the permeability of the cells of the collecting tubule to water is due to an increase in production of ADH. Hormone ADH also called vasopressin is responsible for regulating the amount of water in the blood and is released from the pituitary gland based on signals from the hypothalamus, which detects the water levels of the blood. When too much water is in the blood, the hormone release is decreased and more water is excreted in the kidneys and thus increasing urine output.
Answer:
Look at the picture below!!!
Explanation:
<span>Transpiration is considered as necessary evil because during CO2 and other gaseous exchange, water also escapes and that could be harmful to the plant.</span>
The amount of energy available as one moves up the energy pyramid decreases substantially.
Explanation:
At each trophic level, energy is lost primarily through heat loss and respiration.
In the image below, 100% of the energy from the plant is not available to the deer. As we move further from the primary producer (in the image below, the green plant), less and less energy is transferred.
