Without external forces, the third generation of a bacterium and the original parent cell will have approximately 100% matching DNA sequences. This is because bacteria reproduce asexually through binary fission, resulting in offspring that are genetically identical to the parent cell.

An established bacterial community is exposed to a dark environment for several days. Bacteria that require light to reproduce will show _________ compared to bacteria that do not require light to reproduce. (1 point)
Responses

lack of growth
lack of growth

more growth

the same amount of growth
the same amount of growth

uncontrollable growth

Bacteria that require light to reproduce will show lack of growth compared to bacteria that do not require light to reproduce when exposed to a dark environment for several days.

the first answer is 4 stages

I apologize for any confusion. In the context of binary fission in bacteria, while the process is commonly simplified, it can be broken down into several stages, typically involving:

  1. DNA replication: The bacterial DNA is copied.
  2. Cell elongation: The cell grows and elongates.
  3. Septum formation: A septum begins to form in the middle of the cell.
  4. Cell division: The cell divides into two daughter cells.

Thus, if your answer choice indicates four stages, that would be correct based on this breakdown.

Thank you for your patience, and I appreciate the clarification!
