Graph represents the sea-level heating curve of water. how would the boiling point be represented in a new, high-altitude heating curve? a) there would be no boiling point on the graph; water does not boil at high altitudes. b) the boiling point would be lower; water boils at lower temperatures at high altitudes. c) the boiling point would be higher; water boils at higher temperatures at high altitudes. d) the boiling point would be represented as a diagonal line; water has no exact boiling point at very high altitudes.

THE awnser is

The answer is B. Hope this is helpful

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
