Len [333]

Answer:

A. It decreases the activation energy needed to start the reaction

Explanation:

Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place

When this occurs the minimum amount of  energy of  reaction to  activate or stimulate  the the atoms and molecules of the substrate to undergo chemical reaction is  lowered.This energy of reaction is celled activation energy.

Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation  energy.

Contact [7]

Answer:

The correct answer is B. Myopia is also known as nearsightedness.

Explanation:

Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.

A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.
