Answer:
50% Hh - short, 50% hh - long
Explanation:
The top of the Punnett square would have Hh and the side would have hh. When crossed, the results would be Hh, hh, Hh, and hh. So half of the offspring have short hair and the other half have long hair.
When the concentration of a certain solute is low inside the cell with respect to the cell's external environment, then the cell performs active transport of the solute from the cytoplasm with a low concentration of solute within the cell to the cell's external with a high concentration of the solute. This process of active transport requires the need of energy in the form of ATP to drive the pumps that are present on its cell membrane.
No they don't. They never cross each other because of the way that they are drawn, similarly to how height is represented. That's why they never cross.
