Answer 1

I can’t see Figure 10–5. Please upload the image or describe what A is pointing to (e.g., the waist of an X-shaped chromosome, one arm of an X, microtubule fibers between poles, or a small barrel-shaped body near a pole).

Quick ID guide:
- If A points to the narrow constricted region joining the two halves of an X-shaped chromosome → centromere.
- If A points to one of the two identical halves of the X → sister chromatid.
- If A points to radiating microtubule fibers between poles → spindle.
- If A points to a small cylindrical organelle at a spindle pole → centriole.

If you tell me which part A indicates I’ll give the correct choice.
