<span>The right answer is D. males have only one copy of the X chromosome.
</span>Hemophilia is a rare hereditary bleeding disorder disease. The blood of hemophiliacs does not coagulate normally. Bleeding is not more important, but without treatment, they can be more frequent and last longer than normal. Hence the importance of good monitoring and good treatment.
<span>The 2 types of hemophilia A and B are recessive and X-linked, but a third of hemophilia correspond to a de novo mutation. It is observed that a man who wears the X is always affected by the disease (because he has only one X chromosome in its genome) whereas the woman is only a carrier (she has two X chromosomes, so it can carry a safe X and a mutated X without being attempted by the disease but can transmit it to her descendants). This must be taken into account for genetic counseling.</span>
animal cell works differently than plant cell
animal cell have million of cell as well plant..
animal cell have four key part ..plant cell have cell wall,chloroplasts, vacuoles
Explanation:
Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants.
Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.
Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present. Large vacuoles help provide shape and allow the plant to store water and food for future use. The storage function plays a lesser role in animal cells, therefore the vacuoles are smaller.
The definition is:genetics definition<span>. The study of heredity, or how the characteristics of living things are transmitted from one generation to the next. Every living thing contains the </span>genetic material<span> that makes up DNA molecules. This</span>material<span> is passed on when organisms reproduce.</span>
It is the motor cortex of the brain that controls the voluntary movements of the body. It is in the rear part of the frontal lobe and is a region in the cerebral cortex. It is responsible for planning, control and the execution of the voluntary movements in the body.
