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.

Answer: Homeostasis is a resistance to change.
Explanation: There are many other examples of homeostasis in biology, like the pH of blood and the concentration of ATP in a cell.
The nurse should try to find an oximetry sensor that is not so tight so that the baby will not feel discomfort and thus respond in that way to the caregiver's concerns and alleviate the problem by taking these appropriate measures.
Answer:
You would expect the accuracy to increase as you caught more fish since you are getting a bigger more precise population sample.
Your answer is A
1.Magnification is the ability of optical instruments, such as a telescope or a microscope, to make an object bigger while resolution is the ability of optical instruments to produce images that are clearer, finer, and sharper.
2.Resolution is the power of an optical instrument to capture and produce more details of an image while magnification is the power of an instrument to create and produce a much larger image of an object.
3.Resolution can be expressed in arcsec or seconds while magnification can be expressed by a whole number and the letter “X.”
4.Although both are dependent upon each other, a high magnification does not always guarantee a high resolution.
5.Magnification allows us to see small objects, especially those that are not visible to the naked eye, while resolution allows us to see these objects more clearly and with more details.
