Answer:
The two main DNA lesions formed by exposure to UVB are cyclobutane pyrimidine dimers (CPD) and 6-4 pyrimidine pyrimidone photoproducts (6-4PPs), and its Dewar isomers.
Answer:
"*Because the lymphatic system collects excess tissue fluid, if it were not working, swelling (edema) would occur in the tissues. The thymus cleanses the blood from the cardiovascular system of cellular debris and bacteria."

In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.
Answer:
Purify peroxidase through metal affinity chromatography
Explanation:
In order to make sure the turnip peroxidase is responsible for the color change of guaiacol and not some other turnip enzyme it would be necessary to purify peroxidase through metal affinity chromatography. For the change of color some factors need to be appreciated too, pH, enzyme concentration and temperature will influence the reaction. Peroxidase is a heme, an enzyme encouraged of the catalyze reaction of hydrogen peroxide.
