Explanation:
The autonomic nervous system regulates peripheral blood flow and sweat glands.
Nerves control muscles connected to hair follicles.
The integumentary system reduces water loss, contains receptors that respond to touch, regulates body temperature, and protects the inside of the body from damage.
The result of abnormal cell division would be about 80-90% chance of being cancer cells caused by a failure of the cell division not wanting to divide the cell.
(The result of this can lead to tumors which can potentialy lead to cancer.)
Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
According to studies, 80% of the data that we take in comes from our power of sight. Sight lets us take in 180° of images, perceive 1 million different colors, adjust what we see based on level of light & focus close up or miles away. Our vision is more detailed than any digital camera.
