Question

1. what structure is responsible for moving chromosomes during mitosis? centriole nuclear membrane spindle fibers cytoplasm question 6 1 pts 6. which event is characteristic of prophase? the cytoplasm divides. chromosomes gather at opposite ends of the cell. sister chromatids separate. chromosomes become visible and the nuclear envelope breaks down.

Explanation:

• Question 5: Spindle fibers form a network that attaches to chromosomes and moves them during mitosis. Centrioles organize spindle fibers but don't directly move chromosomes. The nuclear membrane breaks down during mitosis but isn't involved in chromosome movement. Cytoplasm is the cell's internal fluid and not responsible for moving chromosomes.
• Question 6: In prophase, chromatin condenses into visible chromosomes, and the nuclear envelope breaks down. Cytoplasmic division occurs in cytokinesis. Chromosomes gathering at cell ends is in telophase. Sister chromatids separate in anaphase.

Answer:

• Question 5: spindle fibers
• Question 6: Chromosomes become visible and the nuclear envelope breaks down.
