A. a piece of DNA that controls a trait
Answer:
destruction of infected cells by cytotoxic T cells, or the destruction of intracellular pathogens by macrophage
Explanation:
A cell-mediated immune response is an immune response that does not involve antibodies. Cell-mediated immune responses involve the destruction of infected cells by cytotoxic T cells, or the destruction of pathogens by macrophages.
The answer cannot be either of the options involving B cells, as these are involved in the antibody response. The cytotoxic T cells are what actually destroy the infected cells (not helper T cells). Therefore, the answer is destruction of infected cells by cytotoxic T cells, or the destruction of intracellular pathogens by macrophage
The answer is water. This occurs through the following reaction. During this oxidative reaction of
NADH by O2, the energy expended is used
to synthesize ATP from ADP and Pi. Because NADH generated in the cytosol cannot
enter the mitochondrion, electrons and protons from NADH are transferred in by an electron shuttle system.
Pretty sure its a.) the umbilical cord carries the metabolic waste from the fetus to the placenta where it diffuses into the maternal blood.
Bc metabolic waste just goes from the umbilical cord to the mothers blood
Answer:
decreased mass - less energy needed for movement - less carbohydrates required - more available ATP
Explanation:
Solution; Increased muscle mass in athletes will increase the number of mitochondria in body. Mitochondria provides energy to cells of our body so more mitochondria will results in more energy and due to large amount of energy there will be increased cellular respiration and less fatigue, thus athletic performance will be improved.
