The cell cycle is the cyclically ordered sequence of events taking place in the cells associated with the division of the cell.
The cell cycle takes place in two phases: the interphase proceeded by M-Phase. The interphase of the cell cycle proceeds in G₁, S and G₂ phase. During the G₁ phase, the cell prepares itself to prepare for the next important phase marked by the synthesis or replication of the genetic component of the cell.
The changes that take place during the G₁ phase thus includes the increase in size and the production of ATP as DNA replication is an energy-dependent process.
<h2>During the cell cycle, specifically interphase, a cell must reach a sufficient size and produce enough ATP in order to<u>replicate its chromosomes</u>.. Most of interphase is spent in G1. It is followed by S or the synthesis of chromosomes and then a second growth phase. This phase produces more ATP so the cell can divide. </h2>
Explanation: just got it right on my USATESTPREP its LETTER D.
Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. That causes their genes to become more common in the population over time, and it's the way species evolve to adapt to changes in their environment.
