Question

1. complete the statement with the appropriate image number and vocabulary for the stages of cell division presented in the image

a. □ in this phase the chromosomes cross over to exchange genes and are visible (often look like an x). the nucleus begins to disappear
b □ in this phase the dna is still in the uncoiled, loose format, and phase where the cell spends most of its life.
c. □ in this phase homologous chromosome pairs line up in the middle of the cell.
d. □ in this phase the cell has separated into four unique daughter cells

Explanation:

For part a, the phase where chromosomes cross over (gene exchange) and are visible (X - shaped) with the nucleus disappearing is Prophase I (in meiosis) or Prophase (in mitosis, though crossing over is more typical of meiosis Prophase I). For part b, the phase with uncoiled DNA (chromatin) and the cell's longest - lived phase is Interphase (specifically G1, S, G2; mainly G1 for the "most of its life" part). For part c, when homologous chromosome pairs line up in the middle of the cell, it's Metaphase I (in meiosis). For part d, when the cell has separated into four unique daughter cells, it's Telophase II (in meiosis, as mitosis produces two daughter cells, and meiosis II ends with four unique cells due to crossing over and independent assortment).

Answer:

a. Prophase (or Prophase I)
b. Interphase
c. Metaphase I
d. Telophase II
