Influenza (the flu) is caused by a virus that attacks the respiratory system. which type of gene is most likely to be widely expressed in the body of someone who contracts the influenza virus? a the gene that controls the production of stem cells b the gene that controls the production of skin cells c the gene that controls the production of red blood cells d the gene that controls the production of white blood cells

The correct answer will be option-D

Explanation:

The body responds to a pathogen by producing the immune cells or white blood cells. The white blood cells are produced in the bone marrow.

The white blood cells provide immunity to humans either by eating the pathogen or by killing the virus-infected cells.

If a body is affected by a virus causing influenza, then it will lead to the expression of white blood cell producing genes. The expression of gene will lead to the production of white blood cells which will provide immunity against the pathogen.

Thus, option-D is the correct answer.

it creates acid rain
