Which of the following does not exist during prophase?. Single choice. A. Condensation of chromatins
B. Disappearance of nuclear membrane
C. Pairing of homologous chromosome
D. Chromosomes lined up in the middle of the cell
Option 2

Option B.

Disappearance of nuclear memberane.

Explanation:

This is because Prophase is marks the beginning of mitosis, and it is the process where replicated genetic contents are separated into daughter cells. During prophase, ttgere is condensation of chromatin. The chromatin coils and it become compact, which lead to the formation o chromosomes that are visible. The sister chromatids are joined together at the centromere. The mitotic spindle begins to form. The mitotic spindle is consist of long proteins called microtubules that firms at opposite end. The spindle separate the two sister chromatids.

the correct answer is:

a population changes in response to a change in the environment.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
