Which characteristics of an insect population enable it to adapt and develop
resistance to a pesticide more quickly?

Resistance in insects develops when the same insecticide (or class of insecticides) is used against a pest population over and over again. Some insects will survive the same dose that kills their friends. Those that survive pass on that survival trait to their offspring.

Polarity is when a molecule has a little bit of a charge on one side that's different from a charge on the other side so think of a north pole and a south pole when thinking of polarity.

So polarity is going to be a molecule that has different charges on the molecule so the bigger the difference in charge, the more polar. To make the definition easier, you can say that polarity is a difference in charge across a molecule.

Water is polar because it has a little bit of a negative charge on one end and a little bit of a positive charge on the other end so that's why water would be considered polar.
