hi there
your answer to this is :
“any single identifiable source in the wild is source of pollution. it hurts animals if they eat it,caught in it, or gets cut by it too. Of this pollution from which pollutants are discharged, the toxic waste can really harm the place and cause polltions.
EXAMPLES:
- pipe
- a plastic bottle
- toxic waste
- and more
i hope tis helped out i tried my best
have a great afternoon

Answer:
breeding
Explanation:
its a term that means the same thing as reproduction
If the new compound breaks down into amino acids and functions to break down organic matter into food for the plant, then the researchers discovered a biological catalyst.
<h3>What is an enzyme?</h3>
An enzyme can be defined as a special type of biological catalyst that helps to speed up the rate of a given chemical reaction.
Enzymes are proteins that can be considered as the main class of biological catalysts, but there are also other biological catalysts called ribozymes which are specifically composed of nucleic acids, i.e., RNA-based catalysts.
In conclusion, if the new compound breaks down into amino acids and functions to break down organic matter into food for the plant, then the researchers discovered a biological catalyst.

The structure of a typical antibody molecule
Antibodies are the secreted form of the B-cell receptor. An antibody is identical to the B-cell receptor of the cell that secretes it except for a small portion of the C-terminus of the heavy-chain constant region. In the case of the B-cell receptor the C-terminus is a hydrophobic membrane-anchoring sequence, and in the case of antibody it is a hydrophilic sequence that allows secretion. Since they are soluble, and secreted in large quantities, antibodies are easily obtainable and easily studied. For this reason, most of what we know about the B-cell receptor comes from the study of antibodies.
Antibody molecules are roughly Y-shaped molecules consisting of three equal-sized portions, loosely connected by a flexible tether. Three schematic representations of antibody structure, which has been determined by X-ray crystallography, are shown in Fig. 3.1. The aim of this part of the chapter is to explain how this structure is formed and how it allows antibody molecules to carry out their dual tasks—binding on the one hand to a wide variety of antigens, and on the other hand to a limited number of effector molecules and cells. As we will see, each of these tasks is carried out by separable parts of the molecule. The two arms of the Y end in regions that vary between different antibody molecules, the V regions. These are involved in antigen binding, whereas the stem of the Y, or the C region, is far less variable and is the part that interacts with effector cells and molecules.
