C, because it makes the most sense hoped this helped !!!!!
The answer is; cell surface receptors that are recognized as antigens by the recipient's immune system.
Therefore the organ is attacked as a foreign substance . This is why organ transplants are given by the closest family member to reduce the antigen variability that causes transplant rejection. Tissue typing is done to ensure that the organ or tissue is as similar as possible to the tissues of the recipient.
Answer:
True
Explanation:
In inhibitory postsynaptic potentials, the opening of chlorine and potassium channels generally occurs so that chlorine enters, with a negative charge, and potassium leaves, with a positive charge. The synergistic effect of this ionic flow is the hyperpolarization of the cell, making it difficult for an action potential to occur.
Answer
The correct order to describe the carbon cycle would be;
• The carrot plant takes in carbon dioxide from the air during photosynthesis(3)
• The rabbit eats the carrot plant(2)
• The rabbit decomposes(1)
• The carbon compounds are returned to the soil (4)
Explanation
Carbon is captured in the food web through autotrophs (carrot plant) which undergo the process of photosynthesis. The captured carbon will utilized in making organic compounds (glucose). Heterotrophs (the rabbit) will feed on the carrot to allow the organic carbon to proceed into the food chain. Decomposers (acting on dead rabbit) release organic compounds and carbon iv oxide during breaking down of the decomposing matter. Biologically carbon is returned to the environment and soil after this stage.
