Students are investigating temperature changes on substances in their gaseous state. Which of the following is most likely to happen to the gaseous substance when the students decrease the temperature?

Why are favorable traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
Because they come from dominant alleles.
Because they come from recessive alleles.
Because the trait is an acquired phenotype.
