determined?

1. explain the differences in the cells below. (be sure to discuss how they

are made)

Explanation:

The questions are about meiosis, cell types, genetic variation, nondisjunction, and chromosomal mutations, which fall under Biology (a subfield of Natural Science). For question 1 (function of meiosis): Meiosis reduces chromosome number by half (from diploid to haploid) to form gametes, enabling sexual reproduction and genetic diversity.

Answer:

1. The function of meiosis is to produce haploid gametes (sperm and egg cells) by reducing the chromosome number by half (from diploid, \(2n\), to haploid, \(n\)) and to introduce genetic variation through processes like crossing - over and independent assortment, which is essential for sexual reproduction and evolution.
