• mitosis is the division of the cell
• mitosis is the division of the chromosomes/nucleus
• mitosis is the division of sex cells (egg & sperm cells)
• mitosis is the division of the cytoplasm

which statement is the best description of meiosis? *

• meiosis is the division of sex cells (egg & sperm cells)
• meiosis is the division of the cytoplasm
• meiosis is the division of the cell
• meiosis is the division of the chromosomes/nucleus

how many chromosomes are in a normal diploid (2n) human somatic cell? *

• 32
• 23
• 46
• 64

Explanation:

Define mitosis and its primary function

Mitosis is specifically the division of the nucleus and its genetic material (chromosomes), distinct from cytokinesis (cytoplasm division).

Define meiosis and its primary function

Meiosis is a specialized form of nuclear division that reduces the chromosome number by half, specifically producing haploid sex cells (gametes like egg and sperm).

Determine human diploid chromosome number

A normal diploid (\(2N\)) human somatic cell contains exactly 46 chromosomes (23 pairs).

Answer:
