fenix001 [56]

Answer:

The phenomenon that explains the trend seen in the data is that the mosquitoes' evolution has led them to develop resistance to the compound.

Explanation:

This is a very common factor that we can see in insects. The effect of DDT on the species will have different levels of impact. One is going to be more vulnerable to the compound that the rest. However, after many times of exposition to the compound, a few survivors will develop resistance to the compound and their offspring is going to inherit that resistance. Making them increase the resistance over time.

What effect would you predict acrylamide treatment would have on the mechanical rigidity of a keratinocyte (skin cell)?
Lubov Fominskaja [6]

Answer:

C is surely the answer

C. Disrupting intermediate filaments will result in cells that are more susceptible to mechanical forces. In the case of the keratinocytes, disrupting keratin, a key IF in these cells, would result in very fragile cells. Less force would need to be applied using the magnetic beads to damage them or change their shape.
