Explain why respiratory surfaces must be moist​

Biology

Answer:

In animals, the process of respiration is aerobic respiration, exchange of gases takes place ( carbon dioxide leaving the cell, oxygen entering)

Single cellular organisms can exchange gases directly across their cell membrane through the process o diffusion.

Large animals cannot maintain gas exchange by diffusion across their outer surface. A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.

Exocrine glands secrete sweat and oil while endocrine glands secrete hormones.

Explanation:

As she knows the endocrine and exocrine glands in respect of their origin from skin, so our answer must be related to the skin so that she can understand easily. So our answer should be as follows -

  • Endocrine glands are those glands which secrete hormones directly to the blood stream but exocrine glands are those glands which secrete sweat and oils directly to the skin surface.
  • A duct is often present in exocrine glands but endocrine glands lack ducts.

A hypothetical poison prevents nucleoli from carrying out their functions.
ruslelena [56]
If a hypothetical poison prevent nucleoli from carrying out their functions, the cell organele that will be affected is the RIBOSOMES.
Nucleoli of the cell is the one that is responsible for production of ribosomal sub units; it uses proteins and ribosomal RNA to do this. It then send the sub units to the interior of the cell where they are assembled.
Ribosomes make proteins in the cells. Thus, if nucleoli is affected, ribosome will not be produced and ultimately proteins will not be produced in the cells.
