Answer:
Temperature is an essential aspect in any experiment as it can affect the various variables of the experiment. It can affect the result and outcomes of an experiment as per the interaction various molecules shows with the temperature.
In molecular biology related experiments that deals with the protein related experiments are also effected by the temperature as enzymatic reactions are slow on low temperature and proteins are also act like enzymes. On high temperature protein may lead to increase in collisions of the molecules of protein and fasten the enzymatic reaction and may lead to degrade the protein.
Well, experimentation can be really expensive, so when funding is provided it gets rid of a lot of obstacles.
I think option one because if the molecules are moving in place, they are tightly packed like a solid. if they are moving around each other, that would mean they could move more freely like a liquid.
