Duchene muscular dystrophy, or DMD, is a recessive, x-linked disease. What would you expect to see in the offspring of a woman w
Harman [31]

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.

Electrons are passed to oxygen through a chanin of carriers in the inner mitochondrial membrane.
jenyasd209 [6]

Answer:

b. Mitochondrial respiration

Explanation:

Mitochondrial respiration of plants involves the participation of two major electron transport routes:

1. Cytochrome c oxidase route: cyanide sensitive and coupled to three energy conservation sites.

2. Cyanide-insensitive alternative route: involves alternative oxidase (AOX), branches off the cytochrome oxidase route into the ubiquinone pool, with no energy conservation thereafter as AOX is able to directly oxidize ubiquinol and reduce oxygen to water.

Regardless of the route followed, mitochondrial breathing is a long and complex process. However, it is through this breath that at a given moment electrons are passed to oxygen through a carrier channel in the inner mitochondrial membrane.  This happens when cytochromes to and some molecules that have a heme group (with an iron atom) and are linked to a transmembrane protein that connects the matrix to the mitochondrial intermembrane space and have two copper atoms that allow the transport of electrons to the final acceptor, oxygen (O2).
