<span>D.Oxygen will diffuse from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell). This is because cells respire constantly, as this process uses up oxygen cells will contain less oxygen than its surroundings. Oxygen moves by the process of diffusion, in diffusion a molecule will always move from a higher concentration to a lower concentration.</span>
The correct answer would be A
Answer:
If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.
Explanation:
This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.
The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.
