Meiosis is the process of cell division that starts with 92 chromatids, hence the correct answer is meiosis.
Cell division known as meiosis creates four daughter cells with half as many chromosomes as the parent cell. This is crucial for sexual reproduction because it enables the progeny to have a diverse chromosomal makeup from their parents.
Meiosis I and Meiosis II are the two stages of meiosis. The chromosomes multiply during meiosis I but do not split. As a result, each daughter cell has 92 chromatids; yet, they are still joined at the centromere.

Which of the following is the control group in this experiment?
The control variable is a group that serves as a baseline for comparision. The independent variable is not applied or only applied at a baseline level.
The independent variable is the covering of the ice with different materials. Because group 4 wasn't covered, it is the control variable.
The control group in this experiment is group 4, which remained uncovered.
In an experiment, the control group is the group that does not receive any treatment or manipulation. It serves as a baseline for comparison to the other groups. In this case, the control group is not covered with any material, which means it is not subjected to any additional factors that could affect the melting rate of ice.
By comparing the results of the other groups (group 1 covered in plastic, group 2 covered in paper, and group 3 covered in aluminum) to the control group, the researchers can determine the effect of different materials on the melting rate of ice.
I hope this helps you. :)
