I would have to say that A is the correct answer.
Answer:
a. The spindle apparatus is present in cells undergoing <u>mitosis and meiosis. </u><u> </u>the spindle is crucial for chromosome sorting.
b. Chromosome replication occurs just prior to <u>mitosis and meiosis I. </u> DNA needs to be copied during S fase to have enough DNA and transfer it to the daughter cells.
c. The cells resulting from <u>mitosis </u>in a haploid cell have a ploidy of n.
Mitosis produces identical cells.
d. The cells resulting from <u>meiosis II </u>in a diploid cell have a ploidy of n. meiosis is the only process that causes chromosome reduction (assuming no errors).
(e). Homologous chromosome pairing regularly occurs during <u>meiosis I.</u> Each daughter cell needs 1 chromosome of each kind
(f). Non-homologous chromosome pairing regularly occurs during <u>none</u>. This is kind of an error.
(g). Physical recombination leading to the production of recombinant progeny classes occurs during <u>Meiosis I </u>
(h). Centromere división occurs during meiosis II and mitosis
(i) Non-sister chromatids are found in the same cell during <u>meiosis II</u>

Answer:
- Label A - G1 phase
- Label B - S phase
- Label C
- G2 phase
- Label D - Mitosis
- Label E - interphase
Explanation:
Label A - G1 phase (First gap phase): during this phase, cell grows, forms more protein, RNA and copies cell organelles.
Label B- S phase (Synthesis phase): during this phase, synthesis of DNA and its replication occurs.
Label C- G2 phase (Second Gap phase): during this phase the cell grows more, makes protein and cell organelles.
Label D – Mitosis: during mitosis the cell divides its nucleus and cytoplasm to produce two daughter cells.
Label E- Interphase : A stage of cell growth and metabolic activity. The G1,S and G2 phases together called interphase.
