<h3>How are gene variants involved in evolution?</h3>
Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from genetic variations (also called mutations) or from a normal process in which genetic material is rearranged as the cell is about to divide (known as genetic recombination).
Genetic variations that alter gene activity or protein function can introduce different traits into an organism. If a trait is beneficial and helps the individual survive and reproduce, the genetic variation is more likely to be passed on to the next generation (a process known as natural selection).
Over time, as generations of individuals with the trait continue to reproduce, the favorable trait becomes more and more common in a population, making that population different from the ancestral population. Sometimes the population becomes so distinct that it is considered a new species.

Vascular neurocognitive disorder
is a condition caused by reduction or blockage of the brain’s blood supply. Because of the lack of blood, a certain region of the brain was damaged, changing a person’s
brain functions.
Answer:
The dominat character can express two genes of a character even one of the genes.
Explanation:
If there was once a fish there then that would mean the habitat of a fish was once there but dried up. a lake or river or even an ocean could have once been there but dried up and left a fish fossil
Answer:
based on a tested hypothesis
Explanation:
Laws are generally <u>based on tested hypotheses</u>.
Theories are first derived from repeatedly tested and proven hypotheses. Scientific laws are derived from theories that have been proven to be true over a wide range of phenomenon. Hence, laws are overwhelmingly proven facts that <u>cannot be changed</u>.
Scientific laws are <u>internally consistent</u>, compatible with evidence, and are <u>testable against a wide range of phenomenon</u>. However, <u>they can be reviewed</u> as more evidences emerge that have not been known before.
