The answer is B. A chemical reaction consists of an endothermic stage (energy taken in to break chemical bonds) followed by an exothermic stage (energy released as bonds are formed). The first stage requires this energy input, which is the activation energy. When the activation energy is reached or exceeded, the reaction will occur. Therefore as soon as this threshold is REACHED, it happens
Answer:
DNA's information can expressed through flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions
