The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions which are described as so because their amino acid sequences can be different on different antibodies.
The specificity of antibodies is determined by the variable regions found at their endpoints. Antibodies are specialized proteins secreted by B-cells of the immune system. They are also called immunoglobulins. They contain four polypeptide chains that comprise two heavy chains and two light chains to form a Y-shaped molecule.
The variable regions, more specifically the hypervariable regions of an antibody, have a high ratio of different amino acids with the most common amino acids provided in one place. The variable region serves as the antigen-binding site while the constant region found below the variable region is determined to invade the antigen.
Antibodies are preserved in our body to identify the antigen the next time it encounters. They send the signals to the other body parts to reject the antigen and invade it.

Answer:
If you don't continue an accurate antibiotic treatment, compliting it course, you encourage development of antibiotic resistance in bacteria, which can become difficult to treat with the same antibiotic or cause a bacterial regain and cause a severe infection. It can also become life -threatening in the future leading to difficult results in treatment with the same antibiotic or others.
Explanation:
No. The recorded drop in water in the pipet of the potometer would have been used not only for plant transpiration, but also to return the plant cells to a turgid state. Turgid means to expand<span> due to high fluid content. Plants are required to maintain turgid cells to maintain an upright position as loss of turgidity results in plant wilting.</span>
A mother passes on her mt(DNA) or mitochondrial DNA which sometimes includes genetic material but a father only passes down a Y chromosome if he has a son. No genetic material.
Answer:
that depends on what you were testing for but is it always good for it to come up negative for any diseases
