Answer:
Men express all the X-linked genes present in their genome.
Explanation:
Human males have one copy of X and one copy of Y chromosomes. They express all the alleles present on their X chromosome irrespective of its dominant or recessive nature. This occurs because males do not have a second copy of the X chromosome to carry another allele for the same gene. Color blindness is caused by a recessive allele present on the X chromosome. Males carrying one copy of this allele exhibit the disease while females need two copies of the allele of color blindness to express the disease. Therefore, males are more frequently affected by this disease.
The pH scale ranges from 0 to 14
The answer is C.
A. There is no exchange of water between organisms.

C. An animal consuming an organism involves two organism that both contain water. One absorbs the other’s water through digestion.
D. A plant absorbs nutrients from the soil. This could also be correct as there are organisms in the soil losing water through decay. However those organisms aren’t identified in the statement. This means that C. is the best answer.
