Answer:Sugar molecules contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins and DNA)
The answer to this question should be: Calvin cycle
Calvin cycle is a chemical reaction that was done in the chloroplast of a plant. This is one of the reactions in photosynthesis. In Calvin cycle, carbon dioxide and water will be used to make carbohydrates(glucose). This reaction is forming energy using the sunlight so only autotrophic organism capable that will be able to do it.
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
Because DNA having cross over can cause differentiation.
B. They are able to produce their own food.
