Suppose that a genetic alteration resulted in the synthesis of cyclin-dependent kinases that no longer provided the "go" signal at the cellular checkpoint. Predict the immediate outcome if this were to alter the normal cell life-cycle processes at the G2 checkpoint. The cells involved would
a. grow and otherwise function undergoing mitosis
b. exit the cell cycle completely and enter a nondividing cellular state
c. most likely remain in suspended metaphase, unable to enter anaphase
d. proceed as normal, enter the G1, S, G2, and M phases and divide

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
