question 1 (1 point) saved
which cell cycle stages are part of interphase?
a) g1, s, g2
b) metaphase
c) prophase
d) anaphase
question 2 (1 point) saved
why do cells need to divide?
a) growth
b) reproduction
c) replacement of tissues
d) all the above

Explanation:

• Question 1: Interphase is the phase of the cell cycle where the cell prepares for division. It consists of three stages: G1 (gap 1 - cell growth), S (synthesis - DNA replication), and G2 (gap 2 - further growth and preparation for mitosis). Metaphase, prophase, and anaphase are stages of mitosis (the division phase), not interphase.
• Question 2: Cells divide for multiple reasons. Growth (increasing the number of cells in an organism), reproduction (asexual reproduction in single - celled organisms or gamete formation in sexual reproduction), and replacement of tissues (e.g., skin cells constantly being replaced) are all valid reasons. So, all the options (a, b, c) are correct, which means option d is the right choice.

Answer:

• Question 1: A. G1, S, G2
• Question 2: D. all the above
