Vitiligo occurs in people who are born with normal skin pigmentation as opposed to albinism when an individual is born without skin pigmentation (lack active melanocytes).
Explanation:
To Find :
The recombination frequency between these two mutations.
Solution :
Formula of calculating recombination frequency is :
Putting all given values in above equation, we get :
Therefore, the recombination frequency between these two mutations is 0.01 or 1 %.
The independent variable is the type of exercise that you do to change your resting heart rate.
The dependent variable is the heart after you do said exercise.
The correct anser is option (A) During an especially cold winter, brown squirrels that had thick coats survived at higher rates than brown squirrels whose coats were not as thick.
Natural selection is a mechanism of evolution proposed by Charles Darwin. It is the differential survival and reproduction of individual due to the difference in the phenotype. Over time, this process results in populations which are better adapted to their environment as they tend to survive and produce new offspring. The brown squirrels with thick coat survive at a higher rate than the brown sqirrels without the thick coat. Thick coat is a adaptation for survival in cold winters which are chosen over the other and allowed to reproduce.
the answer is b. energy and matter can enter and leave.
