Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.
The correct answer is XHXH.
Hemophilia is an inherited genetic disease, which damages the tendency of the body to produce blood clots, that is, a procedure required to inhibit bleeding. Hemophilia A and B are both X-linked recessive disorders, though the females are hardly influenced.
X-linked recessive inheritance refers to a kind of inheritance in which a mutation in a gene on the X-chromosome makes the phenotype to be articulated in males hemizygous for the mutation of the gene, as they exhibit one X and one Y chromosome.
