How do glucocorticoids enable the body to deal appropriately with stress? by releasing the neurotransmitters that prepare the bo
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.

Nataly_w [17]

Answer:

E-You disagree because the resulting increase in phytoplankton at the surface would inhibit sunlight from penetrating into the water, thus inhibiting photosynthesis in the submerged plants.

Explanation:

Eutrophication is the process wherein nutrients specifically phosphorus and nitrogen are present in excess in a water body such as a lake. The increased concentration of nutrients promoter the growth of cyanobacteria and algae such as phytoplankton.

The increased population of phytoplankton in surface water reduces the oxygen availability and clarity of water for the organisms present in deeper layers.  Also, reduced clarity of water limits the amount of solar radiations penetrating the surface water to reach the deeper layers.

Increased nutrient levels of the lake would rather inhibit the growth of submerged plants due to reduced availability of sunlight as caused by presence of phytoplankton in surface water.

What would be the result IF DNA did not
stellarik [79]

Answer: The daughter cells develop after the cell division will have unequal number of chromosomes.

Explanation:

The interphase is the stage of the cell cycle in which the parent cell prepares itself for division. It increases in size and develops organelles for cell division. Before the cell division the replication of the genetic material in the form of DNA is necessary so that both daughter cells receive equal amount of genetic material after the cell splits by mitosis. Mitosis is a cell division in which the parent diploid cell splits into two haploid daughter cells. Each daughter cell receives the half the chromosomes as that of the parent cell.
