ANTONII [103]

The responses observed in type IV hypersensitivities result from the action of T cells and phagocytes.

Hypersensitivity IV type, also called delayed-type hypersensitivity (DTH), involves T cell-antigen interactions that cause activation and secretion of cytokines. This type of hypersensitivity requires sensitized lymphocytes that respond 24–48 hours after exposure to soluble antigens. A type IV hypersensitivity reaction is a cell-mediated reaction that can occur in response to contact with certain allergens, resulting in what is called contact dermatitis, or in response to certain diagnostic procedures such as the tuberculin skin test. Certain allergens need to be avoided to treat this condition. Type IV hypersensitivity response is observed results from the action of T cells and macrophages while other types are mediated by antibodies. This reaction  occurs at least 1–3 days after the initial exposure. Type IV hypersensitivity is the mechanism of many autoimmune disorders.

anastassius [24]

The statement which is true about the inheritance of hemophilia is that it is a recessive trait on the X chromosome. Thus, the correct option for this question is C.

<h3>What is Hemophilia?</h3>

Hemophilia may be defined as an inherited bleeding disorder in which the blood does not clot properly. This can lead to spontaneous bleeding as well as bleeding following injuries or surgery.

Hemophilia is significantly caused by the lack of clotting factor VIII or IX in the blood. In most cases, hemophilia is passed down through families (inherited). Most of the time, it is passed to male children. Several women in the family were carriers of the allele for the disorder, only men ended up actually expressing the disorder.

Therefore, the statement which is true about the inheritance of hemophilia is that it is a recessive trait on the X chromosome. Thus, the correct option for this question is C.
