It is expected to see in the offspring of a woman who has DMD and a man who does not have the disease that all of their sons and none of their daughters will have the disease
Option A.
<h3><u>
Explanation:</u></h3>
Duchene muscular dystrophy, also known as DMD is a recessive, x-linked disease. It occurs when there is a mutation in the dystrophin gene. This mutation further affects the muscles of the body leading it to degenerate and ultimately death.
When a woman with DMD and a man without DMD have an offspring, their daughters and the sons will get the mutated gene signature from the mother as she is the carrier. But since the father has normal genes, the daughters will become the carriers and will not be afflicted by it. This is because the normal X chromosome from the father will be passed on to them. The sons on the other hand will have the disease as they will get one of their mother's X chromosome which would be carrying the mutated gene.
Answer:
Provide nutrients to interneurons
Explanation:
The four main functions of glial cells are: to surround neurons and hold them in place, to supply nutrients and oxygen to neurons, to insulate one neuron from another, and to destroy and remove the carcasses of dead neurons.
Epstein (1965) presented observers that photographs of a quarter, dime, and half-dollar were all equal in physical size. The photographs were at the same distance from the observers. Using only one eye the observer said that <span>the dime was closest, the quarter was farther than the dime, and the half dollar was farthest of them all. Using two eyes this was not the result, because they were aware of the distance. So, t</span>his Epstein's results showed that familiar size is most effective when other information about depth is absent.
