5.
The theory of evolution by natural selection means that what is changing over time?
a)
The inherited traits of a population.
b)
The acquired traits of a population.
c)
Hair color and eye color
d)
Attractive features.
6.
Why are advantageous traits more likely to be passed onto offspring?
a)
Because they are more likely to survive and reproduce.
b)
Because they come from dominant alleles.
c)
Because they come from recessive alleles.
d)
Because the trait is an acquired phenotype.
7.

a)
DNA
b)
tRNA
c)
genotype
d)
phenotype
8.

9.
A population of plants live in a field. The plants lose water through their leaves. Their stems store water. What will most likely happen if the environment becomes drier?
a)
Each plant will evolve thicker stems and smaller leaves
b)
After 1 generation, most of the plants will have very thin stems
c)
Plants with larger leaves will be more likely to pass on their traits to their offspring
d)
After several generations, most of the plants will have thicker stems and smaller leaves
10.
Some organisms have colorful appearances to warn their predators (animals that would try to eat them) that they are harmful or do not taste good. If other species, that are not harmful, mimic these colors how would that help them reproduce?
a)
The bright colors would help them attract more mates and allow them to reproduce
b)
Because they have similar colors they can mate with the harmful species to create hybrids
c)
Bright colors help them be more visible in the dark and most mating occurs after dark
d)
The similar markings and colors will increase their chance of predators avoiding them and allow them to survive to reproduce
