The hormone in turn cause sympathetic nervous system activation and increase energy levels, INCREASE RESPIRATION, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a RISE IN BLOOD PRESSURE.

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.
