Weathering is the decomposition of rocks, soils and their minerals through direct contact with the Earth's atmosphere. Erosion is displacement of solids (soil, mud, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms. Erosion occurs because of factors like wind, water, ice, human activities like deforestation etc. Weathering, on the other hand is caused by contact with the earth's atmosphere. These atmospheric conditions may be heat, pressure etc.
That's how they are different.
Answer and explanation:
Antibodies are structures made of four polypeptides, <em><u>two light (L) chains and two heavy (H) chains that join together and form a molecule shaped like a "Y"</u></em>. This structure is possible thanks to the <u>disulfide bonds</u> that bind light chains and heavy chains together. While the stem of the Y is constant and doesn't change ("<em>constant region</em>"), the tips of the Y, composed of 110-130 amino acids and called "<em>the variable region</em>", vary greatly among the different antibodies and are responsible for the high specificity of these molecules.
<u>This is why we could say that the primary structure of this protein is given by disulfide bridges that twist the antibody and allow it to bind to a protein from the flu virus.</u>
