Describe what happens during each event in interphase:
· First gap:
· Synthesis:
· Second gap:

 There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap).

Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied.

The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.

During the S phase, DNA is duplicated into two sister chromatids, and centrosomes, which give rise to the mitotic spindle, are also replicated.

In the G2 phase, energy is replenished, new proteins are synthesized, the cytoskeleton is dismantled, and additional growth occurs.

Explanation:

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
