The main factor that controls the rate of breathing is..
A.) concentration of carbon dioxide.
If we think about it.. When we breath in oxygen, right away it enters your lungs and turns into carbon dioxide. Well since your lungs need to process oxygen and bring oxygen into the blood stream. Then as soon as the oxygen comes inside (inhale) the oxygen turns into carbon dioxide and you breath it out (exhale) to get a new oxygen load.
Makes sense? lol
Good Luck! :)
Answer:
C) dense microvilli
Explanation:
The modification of simple columnar epithelium that allows for efficient absorption along the digestive tract is Dense microvilli.
microvilli increase the surface area of the simple columnar cells allowing more space and opportunities for nutrients to be absorbed from the lumen of the intestine into the bloodstream.
Microvilli are microscopic cellular membrane protrusions that increase the surface area for diffusion and minimize any increase in volume. They are involved in a wide variety of functions, which include absorption, secretion, cellular adhesion, and mechanotransduction.
