The answer to this question would be <span>Feedback Inhibition
Some molecule is dangerous when produced too much. That is why feedback inhibition is needed. If the final product is inhibiting the enzyme that catalyzes the reaction, reaction speed will be decreased as the final product increased. That will help keep the final product amount in a specific range.</span>
A : DNA in the nucleus of the egg controls all cell activities
The answer to the question is A
Yes. Penguins do have knees.
A penguin's leg is composed of a short femur, knees, tibia, and fibula.
It may seem that penguin's don't have knees when they waddle. This is because the upper leg bones of penguins are covered by its feathers, making it appear as though they have very short legs.
I believe the correct answer from the choices listed above is the first option. The processes that rely <span>on the cell’s ATP in order to move substances across the cell membrane would be diffusion, facilitated diffusion and osmosis. Hope this answers the question.</span>
