Why are advantageous 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 organism knew it needed that trait, survives, and passes it on.

Which best describes the role of mutations in natural selection?
Mutations help an organism to better survive in their environment
An organism may acquire a helpful mutation by interacting with the environment
A mutation may result in a beneficial trait that makes an organism more likely to survive and reproduce
Organisms with certain traits are more likely to win competitions for mutations

the more likely it is for some individuals to
evolve
migrate
survive
mutate

Mutations are important because they bring about
death of the organism in which they develop
genetic variation needed for a population to evolve
benefits for the individual, not for the population
changes in genotype, but not phenotype

Why is competition important for natural selection?
It shows which variations are more successful, allowing the organisms with those variations to survive.
It causes organisms, regardless of which traits they have, to die out, reducing the population size.
It causes organisms to get stronger due to having to outcompete other species.
Competition is not important for natural selection.
