Explanation
If insulin cannot bind to the insulin receptor, then GSK3 will not be inhibited, nor will it be able to inhibit glycogen synthase as the activity of kinases such as PKB and GSK3 are dependent on the signal sent out as the response of binding insulin to the receptor. No binding leads to no signal which leads to no activity.
B. Salmonella
Isotonic solutions will have the same or a very similar concentration when compared to the cell or microbe within it. Based on the chart above, Salmonella has a salt concentration as a percentage of volume of 0.9. If the salt concentration of a solution is 1% then 0.9 is the closest compared to the others. Paramecium will be hypotonic while Amoeba and Plankton would be hypertonic in this solution.

The diagram is not attached but the question can be solved with the question alone, since the necessary information was provided.
• D. Offspring D (ff EE)
Explanation:
This is a cross involving two genes in mice. The two parents mice are crossed to produce four offsprings. The genotypes of the parents mice are FFEe (black fur) and ffEe (white fur).
These two parents will produce the following allelic combinations of gametes;
FFEe- FE, Fe, FE, Fe
ffEe- fE, fe, fE, Fe
Using these gametes in a pumnet square (see attached image), 16 possible offsprings will be produced with only three (3) distinct genotypes viz:
FfEE (4/16)
FfEe (8/16)
Ffee (4/16)
Hence, based on this question, all of the offsprings except offspring D (ffEE) is likely to be produced. This means that the offspring with genotype ffEE is the imposter as the parents mice with genotypes FFEe and ffEe could not have given birth to such offspring.
