Answer:
The decrease in the amount of daylight in winter causes a change in gene expression, which results in foxes growing a lighter - appearing coat.
Explanation:
With less quantity of sunlight during winter days, the arctic fox is not able to produce melanin, the natural pigment that changes the hair color into brownish color. In summer days, is the opposite effect, in this way, the hair of the fox turns into brown - gray color.

Explanation:
Symptoms of infection indicate that the body is trying to combat invading microorganisms. Fever for example is a very common symptom with which the body is defending itself against external organisms. The body uses fever as a great weapon because when the body raises up temperature, many of the organisms causing infectionwill tend to be destroyed. For this reason, fever should not be abolished with medicine. It should be maintained in a point were the foreign organisms are killed and the body is protected.
The symptoms such as head ache, fever, tiredness and several other, should be respected, monitored and if it is the case, treated with medicine in case the "battle" of the invasors against the body are winning the battle.
Microarray data attached
Answer:
B, D, E are consistent with the data in the microarray
Explanation:
A) False, if you look at the microarray graph, Gene K is red on the right side of the graph (where patients in group II are) and generally more blue on the left side where group I patients are, meaning it is less expressed
B) This is true, look for example at gene F, individual 3 expresses it strongly, whereas individuals 6 and 7 are quite low.
C) No - microarray data looks at the expression of genes, not the genes themselves.
D) Yes, you can see that generally, genes B-Q are highly expressed in group II patients but not group I. In contrast, genes F-U are not expressed in group II but more expressed in group I.
E) Yes, although the data is not always consistent, there are clear patterns in group II patients not present in group I.
