Viruses act like they are part of your body, attaching to a cell and injecting its genetic material into the cell. The cell doesn't realize it is a virus injecting the genetic material and copies the instructions it does this over and over until it reaches a critical point What is this critical step?What is the final order? Why does this final step cause problems?

Answer & explanation:

The role of viruses is to infect specific cells and alter their metabolism in order to produce more viruses, from which, at a certain moment, the cell "bursts". Once this happens, thousands of new viruses repeat the process in other healthy cells.

The increase in the amount of virus in a organism (viral load) consequently increases its ability to cause symptoms (virulence), at a certain point, when the viral load reaches a specific amount, the body is able to produce defenses on its own (in most cases, virus treatment occurs this way).

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
