Question

a student that is studying cell division sees chromosomes lined up in the middle of a cell. what will happen after this phase? select all correct answers. a loose dna will be packed into chromosomes b chromosomes move away to opposite ends of the cell c the cytoplasm divides d spindle fibers form

Explanation:

• The phase described is metaphase (chromosomes lined up in the middle).
• In anaphase (next phase), chromosomes move to opposite ends (B).
• Cytokinesis (cytoplasm divides) occurs after telophase (not immediately after metaphase, but in some cell division overviews, if considering the overall process, in mitosis after anaphase (which is after metaphase) comes telophase and then cytokinesis. But if we consider the immediate next step in the nuclear division part (mitosis stages: prophase - metaphase - anaphase - telophase), anaphase (chromosome separation) is next. However, if the options are considered in a more general cell - division (mitosis + cytokinesis) context, after metaphase (nuclear division stage), anaphase (chromosome movement) occurs first (as part of mitosis) and then cytokinesis. But in standard mitosis stage order, after metaphase is anaphase (chromosome separation - B) and then telophase and cytokinesis. But since B is about chromosome movement (anaphase) which is the immediate next in nuclear division (mitosis proper), and if we assume the question is about the mitotic phase sequence (not considering interphase etc. in a complex way).
• A (DNA packing) is in prophase. D (spindle fiber formation) is in prophase.

Answer:

B. Chromosomes move away to opposite ends of the cell
