I'm trying to localise a protein called "Protein B."

I've made a vector which encodes protein B that is tagged with an epitope derived from the flu virus. This vector is then transformed into a human cell line, and antibodies to the flu virus will be used to locate the protein.

2 staining procedures are done, one with no alcohol, and one with 2% (v/v) alcohol.

In the staining with no alcohol, you can see uniform staining of the area outside the nucleus.

In the staining with 2% alcohol, you see speckled staining in the area outside the nucleus.

I know that protein B is located in the mitochondria/cytoplasm.

My question is: What does the uniform staining vs speckled staining indicate? Also, why does this type of staining occur?

In an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. He studies two set of people—those who exercise every day for an hour and those who don’t exercise at all. In this case, the statement that people who exercise for an hour may have lower cholesterol levels is____. To test this statement, the scientist would measure cholesterol levels in exercisers and non-exercisers. The cholesterol levels would be___.
