Actually, heavier objects fall faster. The difference is infinitesimal, but there is a tiny difference because more mass causes objects to fall faster (e.g. objects fall faster on earth than on the moon). On earth, the different rate of fall between heavier and lighter objects is negligible (because objects are tiny compared to the earth's mass), so objects of different weights fall at virtually the same rate. But not at exactly the same rate. Objects of different weights must accelerate at different rates because accel.

Answer:
It can lead to melanoma or a time of skin cancer.
Explanation:
This is because UV radiation in sunlight can destroy the DNA by destroying the base pairing. UV light will cause two Thymine that are very closer to each other to join together to produce dimer. After which, The melanin-assisted process form lesions that is popularly called cylobutane pyrimidine dimers in DNA, which can result in mutations that cause melanoma which is a form of skin cancer
Answer:
Pupillary light reflex refers to the contraction that the pupils present when they light up. In cases of injury to the optic nerve, when the eye where the injured optic nerve is illuminated, since it cannot conduct the stimulus to the brain, neither pupil closes.
Explanation:
Pupillary light reflex refers to the reaction that causes the pupil to close with light thanks to the contraction of the sphincter of the pupil and to open in the dark thanks to the relaxation of that muscle by not receiving any stimulus. A light stimulus reaches the eye and in the retina it is transformed, through a chemical reaction, into an electrical stimulus that will be transmitted through the optic nerve and the visual pathways to the brain. The visual cells of the retina, rods and cones, also act as light receptors that control the pupil's motor activity. Thus, pupil-motor thresholds to light follow the same spectral sensitivity deviations as visual thresholds, which are a function of the state of light adaptation of the retina.
b is the correct answer. hope this helps
