Question

6. Which correctly explains a difference between mitosis and meiosis? *

A.mitosis produces gametes, and melosls produces body cells
B.mitosis has one nuclear division, and melosis has two nuclear divisions
C.mitosis is related to sexual reproduction, and meiosis is related to asexual reproduction
D.mitosis reduces the chromosome number by half, and melosis maintains the same
chromosome number

Answer 1

The correct answer is B. Mitosis has one nuclear division, and meiosis has two nuclear divisions.

During mitosis, a single cell divides into two identical daughter cells with the same number of chromosomes as the parent cell. Mitosis is involved in growth, repair, and asexual reproduction.

In contrast, meiosis involves two rounds of nuclear division, resulting in the production of four genetically diverse daughter cells, each with half the number of chromosomes as the parent cell. Meiosis is involved in the production of gametes (sperm and egg cells) for sexual reproduction.

So, option B is correct as it correctly explains the difference between mitosis and meiosis, which is the number of nuclear divisions involved in each process.

Answer 2

the answer is D.

Step-by-step explanation:

cells produced through mitosis contain DNA identical to the parent cells, whereas meiosis produces cells that are haploid and often genetically different.
