The membrane is permeable to the non-polar molecules like CO2.
Sodium also can diffuse through the membrane but it needs channels (or transmembrane transporters). the same thing for the glucose and the starch (these transporters can transport molecules passively or actively).
But the CO2 can pass the plasmic membrane easily without channels because it is partially water-soluble, and it is non-polar, so it has no charges, and can pass through the amphiphile phospholipid molecules.
Answer:
A) increases the permeability of the collecting ducts to water by increasing the number of aquaporins.
Explanation:
ADH is an hormone of the anterior pituitary gland concern with osmoregualtion. When the solute potential of the blood rises , with decrease in water potential , the water levels of the blood drops, the osmoreceptors in the hypothalamus sensed this from the circulatory blood and prompted the hypothalamus to stimulate the anterior pituitary gland to secrete ADH.
The hormone is carried in the circulating blood to the walls of the collecting ducts where it binds with the receptors on the walls of the tubule,which increases the fusing and binding of Aquaporins to the membrane of the collecting ducts to increase re absorption of water back into the blood, raising the water potential of the blood.
It is RNA because it is a single strand
Answer:
microspheres expand by absorbing other molecules until they reach an unstable size, where they then split into smaller microspheres.
