Answer;
-The first antibody is specific for the primary amino acid sequence of TT, whereas the second is specific for conformational determinants.
Explanation;
-Antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction.The specificity of the binding is due to specific chemical constitution of each antibody.
-The amino acid sequence in the tips of the "Y" varies greatly among different antibodies. This variable region, composed of 110-130 amino acids, give the antibody its specificity for binding antigen. The variable region includes the ends of the light and heavy chains.
C. Genes are specific sections of a chromosome. Alleles are different forms of a gene.
Hope this helps.
<span>multiple alleles, three or more alternative forms of a gene (alleles) that can occupy the same locus. However, only two of the alleles can be present in a single organism.</span>
<u>Answer: -</u><u> </u>Magma chamber.
<u>Explanation</u>:-
1. A magma chamber is a cavity which acts a reservoir of magma and it feeds a volcano.
2.A <em>magma</em> is basically a mixture of molten and semi molten rocks.
3. The magma is less dense than the layers of rocks and as a result of this it tends to move upwards towards the surface of the earth but when it encounters a layer of rocks in this upward journey that hinders its movement then it gets collected in a large pool which is known as the <em>magma chamber</em>.
4. These magma chambers are under a great pressure which results in the breaking of the rock which surrounds the magma chamber with time. Once, these rocks break the magma can then travel upwards and this results in volcanic eruption.
<em>Thus, these magma chambers are the cavities containing the magma that feeds the volcano.</em>
