What number should both sides of the equation −7x=14 be divided by to solve for the value of x ?
Both sides of the equation should be divided by -7 to solve for the value of x.
Binary fission, which is the process of cell division in bacteria, can be modeled in two stages. These stages are:
1. Replication: In this stage, the bacterial DNA is replicated, forming two identical copies of the genetic material.
2. Segregation and Separation: In this stage, the replicated DNA and other cellular components are segregated into two separate regions of the bacterium. The cell membrane then starts to grow inward between the segregated DNA, eventually dividing the bacterium into two daughter cells, each containing a copy of the genetic material.
Therefore, the correct answer is two stages.
