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

explain your answer.
a. disrupting intermediate filaments will result in cells that are less susceptible to mechanical forces. in the case of the keratinocytes, disrupting keratin, a key if in these cells, would result in the production of microfilaments and thus very tough cells.
b. more force would need to be applied using the magnetic beads to damage them or change their shape.
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.
d. disrupting intermediate filaments will have no effect on their susceptibility to mechanical forces. in the case of the keratinocytes, disrupting keratin, a key if in these cells, would not change the amount of force needed to be applied using the magnetic beads to damage them or change their shape.

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.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
