Answer:
adenine is the correct answer for first
Because a population is most likely going to survive and go away than a population with very sparable genetic variation.
The right answer is Y (G2 phase).
The interphase is the moment when the cell lives and does everything for which it is programmed. She is also preparing to divide. The steps of the division are detailed below:
Phase G1 (W) comes from a word "GAP" (= interval). During this phase, the cell performs its normal metabolism, it grows to a critical size that will give the signal to move to phase S which consists of replicating the nuclear DNA (X).
Once DNA replication is complete, phase G2 begins (The letter Y). Here, the growth of the cell end, but it will continue to fulfill its functions. During this phase, the centrosomes replicate, they will allow the smooth course of the mitosis. This phase ends by passing the G2 checkpoint, where the mitosis begins.
The shortest phase (Z) is M phase (mitosis / meiosis).
