A dead flu virus cell is injected into the body which in turn makes the body recognize the cell so that when an alive flu virus cell enters the body, the body knows what the foreign cell is and can successfully defend against it.
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy. Oxygenic functions as a counterbalance to respiration; it takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere.
<span>An event in which rain-cooled air hits the ground and spreads out in all directions is called a </span>downburst.
The right answer is C
In the anaerobic mode, the reduction of pyruvate to lactate or ethanol (fermentations) ensures the reoxidation of NADH to NAD + consumed during the oxidation of glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate (reaction 6 of glycolysis). This regeneration of NAD + allows glycolysis to be maintained in the absence of oxygen.
In the aerobic mode, NAD + is regenerated by the respiratory chain.
