<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>
Answer:
D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation
Explanation:
The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.
The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).
The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).
From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.
Thus, Option-D is correct.
Answer:
Lol! Also, what is the question? Or is there no question?
Explanation:
Answer:
An organisms niche is it's role in the ecosystem. This includes what it eats and what it's eaten by, and is usually affected by it's habitat.
An organisms habitat is simply where the organism lives.
Answer:
I would say B
Explanation:
Because atural selection is the mechanism for how evolution occurs over time. Basically, natural selection says that individuals within a population of a species that have favorable adaptations for their environment will live long enough to reproduce and pass down those desirable traits to their offspring.
