DNA polymerase is an enzyme that catalyzes the synthesis of new DNA during the S phase of cellular division. If an organism suffered from a disease that resulted in a lowering of the pH in its body tissues, what effect would this have on the rate of cellular division?

See the answer below

Explanation:

Enzymes are generally proteinous in nature and are sensitive to pH. They have optimal ranges of operation and outside these ranges, they either become deactivated or outrightly denatured depending on how far away the pH is from the optimal range.

Hence, if an organism suffers from a disease that resulted in the lowering of the pH in its body tissues beyond the operating range, it may result in the deactivation/denaturing of the DNA polymerase enzyme which will, in turn, halt the synthesis of new DNA and cause cell division to stop.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
