➷ The correct answer would be D. Products of one process are used as some of the reactants for the other processes.

As you may know, the formula for photosynthesis is:

carbon dioxide + water ==> oxygen + glucose

And the formula for respiration is:

oxygen + glucose ==> carbon dioxide + water

The reactants for one are the products for the other and vice versa. This is why it would be the correct option.

What types of antigen do T cells NOT recognize? What types of antigen do T cells NOT recognize? self-antigens bacterial antigens
Stolb23 [73]

Answer:

Self-antigens are not recognized and attacked by the T cells.

Explanation:

In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.
