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:
* The glucose needed for Cellular respiration is delivered by plants. Plants experience a process known as photosynthesis.
* Photosynthesis can be considered as the contrary process of Cellular respiration. Through two processes known as the light reactions and the dark reactions, plants can assimilate and use the energy in daylight. This energy is then changed over alongside water and carbon dioxide from the environment into glucose and oxygen.
* Since this is the contrary process of Cellular respiration, plants and animals are said to have a cooperative relationship. This implies that plants and animals live respectively and advantage from one another.
Explanation:
Cellular respiration is the process by which the substance energy of "food" particles is delivered and incompletely caught as ATP. Starches, fats, and proteins would all be able to be utilized as fills in cellular respiration, yet glucose is most normally utilized as an illustration to analyze the responses and pathways included.
Answer:
El efecto del material sobre el medio ambiente es el aspecto a considerar.
Explicación:
Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.
