Scientists repeat the experiment to further prove it being correct, and they can replicate is with data, models, and other forms of proof of a correct hypothesis
It is called the cytoplasm. It contains a kind of semi-liquid that contains water, named cytosol!
Answer:
<h2><em><u>12 cups</u></em></h2>
Explanation:
<em><u>Given</u></em><em><u>, </u></em>
No. of cups of water saved by 1 student = 3
<em><u>Therefore</u></em><em><u>, </u></em>
No. of cups of water saved by 4 students = 3 × 4
= <em><u>12 (Ans)</u></em>
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.

<span>Amino acids can be used for energy, or to produce glucose or fat. first, however, the amino acid must undergo (transaminase), which is the removal of the nitrogen group
it is done by alpha-ketoglutarate or oxaloacetate. transaminase generate pyruvate that needed for gluconeogenesis.</span>
