Out of the following given choices;
A) light (L) chain B) constant (C) regionC) variable (V) regionD) heavy (H) chain
The answer is B. This region is called the Fc region<span> and composed of only heavy polypeptide chains only. It is used to classify antibody according to class. There are IgM, IgA,   IgG, IgE, and IgD. Fab is the varying region of the antibody that is significant in binding antigens. </span>

<span>The propositions are:
A light (L) chainB constant (C) regionC variable (V) regionD heavy (H) chain

The right answer is B constant (C) region

<span>The immunoglobulin molecule has two distinct functions:
the first is to bind specifically to molecules of the pathogen that has induced the immune response;
the second is to recruit cells or molecules capable of destroying the pathogen against which it is directed.
These functions are structurally separated on the immunoglobulin molecule.

*The part responsible for binding to the antigen, whose structure is extremely variable from one immunoglobulin molecule to another, is called the variable region. This variability allows each immunoglobulin to recognize a particular antigen. The entire antibody repertoire of an individual is diverse enough to allow recognition of any antigen.

*The region of the molecule responsible for the effector functions does not vary so much. This region is called a constant region although in fact it can exist in five different forms. These five forms characterize the isotype of the immunoglobulin molecule. It is the isotypes that are specialized in the activation of this or that effector mechanism.</span>

How pollution from burning fossil fuels in vehicles can be reduced
Drupady [299]

Explanation:

Incinerators are not helpful in reducing pollution as they produce a lot of ash and smoke so it increases the air pollution by burning of waste.

Solar and wind energy are the clean source of energies replacing the fuels. Catalytic converters reduce the air pollution from the exhaust fumes of vehicles.

A single strand of DNA helix consists of 100 nitrogenous base pairs. On one strand, 36 of the bases are adenine and 24 are cytos
Katena32 [7]
Hello!

For the complementary strand of DNA, 36 Thymine bases and 24 Guanine bases would complete the proper base pairing. 

This is given by the concept of complementarity. A base in DNA has complementarity with only one other base. This complementarity is produced by hydrogen bond interactions.

For DNA, Adenine couples with Thymine and Cytosine couples with Guanine. So the 36 adenine bases will couple with 35 thymine bases, and so on. 

Have a nice day!
