The correct answer is option a. true.
The fossil fuels, including coal and oil are present very deep inside the earth. In the carbon cycle, only fixation of atmospheric carbon dioxide in the organic material takes place. This cycle does not involve the recycling of the fossil fuels.
The burning of the fossil fuels directly release carbon dioxide and other carbon compound in the atmosphere, which was not involved in the cycle when it was present deep beneath the earth and ocean. Hence, the burning of fossil fuels increases the amount of carbon in the carbon cycle.
Explanation:
There are several types of antibodies and antigens, and each antibody is capable of binding only to a specific antigen. ... Antigens are bound to antibodies through weak and noncovalent interactions such as electrostatic interactions, hydrogen bonds, Van der Waals forces, and hydrophobic interactions.
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
