How are individual atoms of oxygen formed in the stratosphere?
a.
individual oxygen atoms are formed when oxygen molecules collide with each other.
b.
individual oxygen atoms are formed in the sun.
c.
individual oxygen atoms are formed during photosynthesis.
d.
individual oxygen atoms are formed when uv rays strike oxygen molecules.

The right answer is Individual oxygen atoms are formed when UV rays strike oxygen molecules.

Atomic oxygen is a component of the Earth's upper atmosphere (mesosphere and low thermosphere) produced by photolysis of molecular oxygen. It plays a role in the erosion of satellites in low orbit and is used in restoration of works of art.

Atomic oxygen is formed by photochemical dissociation of oxygen under the action of ultraviolet (UV) rays.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
