klemol [59]

Answer:

By increasing blood glucose, fatty acid, and amino acid levels

Explanation:

Cortisol, corticosterone, and cortisone are the glucocorticoids released by the adrenal cortex and serve to impart resistance to stress. These hormones stimulate protein breakdown (mainly in muscle cells), gluconeogenesis and lipolysis and thereby increase the concentration of amino acids, glucose and fatty acids in blood.

The amino acids are used by cells for synthesis of new proteins or for synthesis of ATP. Glucose is also used by cells to produce ATPs.

Glucocorticorticoids increase the sensitivity of blood vessels for hormones which in turn stimulate their constriction. The vasoconstriction raises blood pressure. The process of vasoconstriction resumes the normal range of blood pressure which is otherwise dropped by some emergency conditions such as injury and severe loss of blood.

perhaps you have heard that the greenhouse effect can cause a problem if too much heat is trapped. Extra heat is trapped because
Korvikt [17]

Answer:

In the process of photosynthesis, trees tend to take up carbon dioxide and water and convert it into oxygen and glucose. In this way, trees help in reducing the amount of carbon dioxide from the air which is otherwise a source of global warming. The process of photosynthesis also yields oxygen which is beneficial for life on earth.

The trees also store carbon inside them hence, reducing global warming. The more the trees, the more will be the chances of carbon being reduced from the atmosphere and being stored in the trees.

Plant processes like transpiration help to lower the temperature around them. Hence, more the trees, lesser will be the rise in temperature.
