Homework Answers
Answer:
90) At this stage, chromosomes continue to condense. New microtubules form a bipolar spindle. They move one of two pairs of centrioles and centrosomes to the opposite end of the cell. The nuclear envelope starts to break.
- Late Prophase (Mitosis) - Correct Option
91) At this stage, all chromosomes have become lined up midway between the poles of the spindle. At this stage of Mitosis and the cell cycle, chromosomes are in their most tightly condensed form.
- Metaphase (Mitosis) - Correct Option
92) At this stage, sister chromatids of each chromosome move apart and microtubules reel them to opposite spindle poles. Other spindle microtubules push the poles farther apart.
- Anaphase (Mitosis) - Correct Option
93) At this stage, there are two clusters of chromosomes, which decondense. Patches of new membrane fuse to form a new nuclear envelope.
- Telophase (Mitosis) - Correct Option

Match the stage of mitosis with the correct description.
Match the stage of mitosis with the correct description.a. Microtubles that are attached to each chromosome shorten, pulling the sister chromatids apart.b. The chromosomes line up single file in the middle of the cell. Sister chromatids are clearly visible in this stage.c. The chromosomes that were pulled apart reach their respective poles. The chromosomes decondense. The nuclear envelope re-forms. The cytoplasm with organelles divides.d. Chromosomes have replicated and appear as an "X". The nuclear envelope begins to break down. The...
