Answer:
polar microtubules contract, pulling attached chromosomes toward the poles.
Explanation:
Polar microtubules are one of the two types of microtubules that together make the mitotic spindle. The polar microtubules are the ones that extend from each pole to the cell's equator.
At the equatorial region, the polar microtubules from two poles overlap. Also known as non-kinetochore microtubules, the polar microtubules do not get attached to the kinetochores of chromosomes.
The function of the polar microtubules is to assist in chromosome separation during anaphase. The polar microtubules from two poles slide past each other. As they slide, the degree of overlap is reduced and the two opposite poles are pushed apart.
The reduced overlap between the polar microtubules indirectly moves the chromosomes apart as the kinetochore microtubules attach the chromosomes to the opposite poles.

FALSE, although there are many different senses they are the only way you can observe something.
Answer:
The nervous system comprises of the brain, sensory organs and spinal cord. The nerves of the body is used to communicate with all the parts of the body.
The brain and the spinal cord is known as the control system of the body which is helps in taking decisions.
The central nervous system helps in maintaining balance of the body, processing the information and based on that response is generated.
The signals from the brain is sent to various parts of the body and from body the signals are sent to the brain for processing.
Hence, the nervous system helps in sensory, motor and integration part of the body.
