What type of cell helps to stimulate b cells to produce antibodies?
valentinak56 [21]
The correct answer is helper T cells.
<span>The helper T cells are one of the main cells of the adaptive immune system. Their role is to help the activity of other immune cells by releasing T cell cytokines and they are required for almost all adaptive immune responses. The helper T cells activate B cells to secrete antibodies, stimulate macrophages to destroy ingested pathogens, and help in activation of cytotoxic T cells to kill infected target cells.</span>

One method for separating polypeptides utilizes their different solubilities. The solubility of large polypeptides in water depe
Otrada [13]

Answer:

Polypeptides are composed of amino acids, and we know amino acids are differently charged, have different R groups, and also have different isoelectric points. Depending on different isoelectric points and charged groups, the polypeptides can be separated and because a protein has its lowest solubility on its isoelectric point.

So in this question,

(a) (Lys-Ala)3 ; this is highly positively charged (polar) at pH 7 than (Gly)20 which is uncharged except for the amino and carboxyl terminal.

(b) (Glu)20 ; it is highly negatively charged at pH 7 whereas (Phe-Met)3 is much less polar and hence less soluble.

(c) (Asn-Ser-His)5 ; at pH 3, because in (Ala-Asp-Gly)5 the carboxylate groups of Asp residues are partially protonated and neutral, whereas in (Asn-Ser-His)5 , the imidazole groups of His residues are fully protonated and positively charged.

(d) (Asn-Ser-His)5; at pH 6.0; both polymers have polar Ser sidechains, but (Asn-Ser-His)5 also has the polar Asn side chains and partially protonated His side chains.

An ionic bond occurs when _____.
Svetach [21]
<span>Ions are another name for charged atoms. Some elements are electropositive, and some are electronegative. Electropositive elements such as metals like to give up electrons, thus taking on a positive charge. Electronegative elements such as chlorine attract electrons, so they become negative. When electropositive and electronegative atoms meet and exchange ions, they take on opposite charges. Because positive and negative charges attract, these charged atoms become attracted to one another. This attraction forms an ionic bond that keeps the ions together.</span>

Explanation:

<em>because</em><em> </em><em>at </em><em>higher</em><em> </em><em>temperatures </em><em>the </em><em>enzymes</em><em> </em><em>get </em><em>denatured</em><em> </em><em>lost </em><em>their </em><em>shapes </em><em>so </em><em>maybe</em><em> </em><em>its </em><em>4</em><em>0</em><em>°</em><em>C</em><em> </em>
