Answer: the child's phenotype will be normal.

The child will acquire that disease.

Explanation:

The mitochondrial DNA is a small circular chromosome that exists in the mitochondria. The mitochondria is the power house of the cell and all its 37 DNA are essential for a normal function of the mitochondria. the mtdna is passed directly from the mother (through the egg cell) to the child either a male or female but the son cannot pass his mtdna to his child. Thus, if a man with this disease marries a woman not affected, the child's phenotype will be normal. But if the wife has the disease, this willl be passed from her to her child me it a male or female.

To answer this question you must break apart the words given on the right.
“Eco” means life and production. So an ecologist would be someone who studies life and it’s processes. So the correct answer for the first blank would be C. Life Science.

A chemist is one who interacts with day to day elements and sciences that is tactile. So the most appropriate answer would be B. Physical science.

A geologist is someone who studies the earth. As the part of the word “geo,” meaning earth, suggests. So the correct answer here would be A. Earth science.

Finally, “Astro” means space .Astrology is the study of the stars and the sky, for example. So, D. Space science would be the best answer for an astronaut.

I hope all of these are helpful. :)
