Key factors that affect development‚ vary; some are from birth and some are developed as age progresses in a child. In this section‚ our main focus would be to highlight key factors of progress in a child life. As a teacher‚ it is very essential that the child’s progress is kept in front of you at all times. One must also be vary‚ that many factors can affect a child’s progress. 1. Intellectual factor- a child who maybe low in IQ or even a low ability student‚ they may also find it hard to multi

up the rate of reaction without itself being used up in the process. Enzymes provide an alternate reaction pathway by lowering the activation energy needed for a reaction to occur. For two molecules to react they must collide with each other‚ however‚ they have to collide with sufficient energy. Sufficient energy means that between them they have enough energy to overcome the energy barrier to reaction. This is called the activation energy. Even though enzymes can alter the rate of reaction‚ they

Enzymes are very large complex organic molecules that are synthesized by the cell to perform specific functions. These biological catalysts are important because they speed up the rate of the reaction that would otherwise be too slow to support life. Catalase is an enzyme present in the cells of plants‚ animals and

The hypothesis was supported by graph 3 and 6 which both showed that an increase in concentration of the reacting species resulted in an increase in reaction rate. Both graphs have a positive gradient which clearly indicates that concentration increases the reaction rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the solution increases. This decrease can
