Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.

Answer:
Explanation:
The greater the forces of attraction the higher the boiling point or the greater the polarity the higher the boiling point. ... The other molecules are slightly polar and show the increase in boiling point with molecular weight which is normal. Instead, water boils at +100 C, which is very abnormal.
