Based on their function, you would expect melanocytes in the skin to have a higher than usual number of ribosomes.
Ribosomes are cell structures that functions as the site of biological protein synthesis. Ribosomes are present in all living cells where they produce proteins required for many cellular functions. Ribosomes join amino acids together in the order specified by messenger RNA molecules. Ribosomes are made up of two parts which are; the large subunits (which connect amino acids to create a polypeptide chain) and the small ribosomal subunits (which read the RNA).
The answer is 3

Answer:
B.) Diffusion
Explanation:
Since this is oxygen, not water, and it is going from an area of high concentration to low, it is moving with its concentration gradient, it would be diffusion. If it were water, not oxygen, then it would be osmosis, and lastly, if it were moving from an area of low to high concentration, that would be active transport. Semipermeability is a characteristic of cell membranes, not a method of movement.
Answer:
Increase
Explanation:
As CO2 enters the blood, most of it is converted to the carbonic acid in a reaction catalyzed by carbonic anhydrase. The carbonic acid dissociates into hydrogen ions and bicarbonate ions. As the H+ concentration increases, the blood pH decreases. Thus, the increased partial pressure of CO2 produces a more acidic environment. Increasing the volume of air that reaches the alveoli and takes part in gaseous exchange will increase the rate of removal of CO2 from the blood. The reduced CO2 levels in the blood would increase the blood pH.
