What happens if an organism is well adapted to its environment? Please check ALL that apply.

• The organism survives.

• The organism reproduces.

• The organism passes on its favored adaptations to its offspring.

• The organism can't reproduce.

Which color of beetle is the favorable variation?

• green

• orange

Tags

NGSS.MS-LS4-4

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.
