question 5
how does meiosis differ from mitosis?
it increases the number of cells.
it decreases the number of cells.
it reduces the amount of dna.
it increases the amount of dna.

Explanation:

• Mitosis results in two daughter cells with the same number of chromosomes (and DNA amount) as the parent cell.
• Meiosis involves two rounds of division, resulting in four daughter cells (gametes) with half the number of chromosomes (and thus half the DNA amount) of the parent cell. So meiosis reduces the amount of DNA.
• Both mitosis and meiosis increase the number of cells (mitosis from 1 to 2, meiosis from 1 to 4), so options about cell number increase/decrease are incorrect.

Answer:

It reduces the amount of DNA.
