Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. ... Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. Hope this helps
Answer:
SARS- CoV- 2 is a virus that infects human by the oral-respiratory way in which the virus enters the body and these viruses have spikes on their surface made of spike proteins that allow these viruses to bind with the infected cell.
The infected cells have ACE2 receptor that is protein present on the surface of the human cells. Binding allows the structural change in the virus to fuse and enter in the cell where viruses reproduce them selves with the cell with cell system.

Explanation:
The thyroid gland uses iodine from food to make two thyroid hormones that regulate the way the body uses energy. The parathyroid glands are four tiny glands located behind the thyroid gland. The parathyroid glands produce a substance (parathyroid hormone) that helps control the amount of calcium in the blood.
Answer the more carbonic acid in the blood, the lower the pH level is. The amount of carbon dioxide removed from the blood messes with the pH level of the blood. this increases the amount of hydrogen ion concentration in blood and it decreases the blood pH levels
Explanation:
Answer: open more frequently to allow water and CO2 into the leaf tissue.
Explanation: Oxygen and C02 enters into the leaves to gives energy and sugar as food,to enable the plant to grow.
It allows the process of photosynthesis. Photosynthesis is the process whereby green plant and other orgasm manufacture light into chemical energy. Plants through the opening of the leaves breath in carbon dioxide and breath out oxygen. While animal in the other hand breath in oxygen and breaths out carbon dioxide.
The continuous opening and closing of stomata is responsible for photosynthesis.
