Answer:
a structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules
Explanation:
Kinetochores have vvery important role in the cell division-mitosis.
During the metaphase of mitosis, spindle fibers attach to kinetochores. Some of the microtubules bind to kinetochore (kinetochore microtubules) while other don’t: they connect with the microtubules from the opposite pole, stabilizing the spindle.
During the anaphase, kinetochore microtubules pull chromosomes toward poles, helping the sister chromatids separate from each other.
Answer:
3. Homeostasis
Explanation:
The state where our bodies maintain an internal equilibrium is called homeostasis.This process ensures biological systems keep on being stable while adjusting to changing conditions which are essential for survival.Homeostasis involves many chemical reactions for example, body hormones should be synthesized to breakdown other molecules; energy molecule called adenosine triphosphate is broken down to adenosine diphosphate to release energy that is used my enzymes in the body to break /build molecules
