It’s c
Because velocity; just like speed will be distance over time
However on this case it’s displacement over time
Anyway in case ur wondering ,
the only difference between distance and displacement is that displacement requires a direction
so
100m/4s
=25 m/s to the east since the direction is already mentioned in question
Answer:
C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.
Explanation:
The terminal part of distal convoluted tubules has two different types of cells: principal cells and intercalated cells. These cells are also present throughout the collecting duct. The principal cells serve to reabsorb Na+ and secrete K+ and have receptors for aldosterone and antidiuretic hormone (ADH).
The function of intercalated cells reabsorb HCO3 - and K+ and to secrete H+. Angiotensin II stimulates the adrenal cortex to release aldosterone which in turn stimulates the principal cells in the collecting ducts to reabsorb more Na+ and secrete more K+. The increased reabsorption of Na+ facilitates reabsorption of more water to increase blood volume and blood pressure.
It is the second one epidermis
Answer: Glycolysis occurs outside the mitochondria in the cytoplasm of the cell.
Glycolysis is a metabolic process in which glucose is broken down into two molecules of pyruvate ( 3 carbon containing molecule) and produces energy molecules as 2 ATP ( adenosine triphosphate) and 2 NADH molecules. Glucose is one of the most important energy fuel that is utilized by living organisms.
Glycolysis occurs in the cytoplasm of all living cells. Thus, it occurs outside the mitochondria.
The answer is hydrogen bond.
Between water molecules, hydrogen bonds can be seen, which is due to the polar nature of water.
