Organisms with a non-adaptive trait:
have more mutations.
have a stronger chance of survival.
have less chance of survival.
have less mutations.
Which population has more variation?
Population A
Population B
Both populations have equal variation
All of the above
Traits that help an organism to survive and reproduce are considered:
Vestigial
Adaptive
Non-Adaptive
Mutation
Different types of traits in an organism, such as fur color, are called:
Evolution
Offspring
Variations
Vestigial
What caused the change in poison levels from 50 generations to today?
A predator
A mutation
A variation
A vestigial structure
Survival of the fittest refers to:
Vestigial
Histogram
Mutation
Natural Selection
Sudden changes that form new traits in an organism are:
Natural selection
Mutations
Adaptations
Evolutions
After 50 generations, the temperature for population A has decreased. Which fur amount trait is most likely to survive?
1
3
5
7
A population of snakes have a variation of green and brown colored scales. The environment goes through a drought over many generations. Which trait is likely to be adaptive?
Green
Brown
Both
Neither
Traits that make survival more difficult are considered:
Vestigial
Adaptive
Non-Adaptive
Mutation
Organisms with an adaptive trait:
have more mutations.
have a stronger chance of survival.
have less chance of survival.
have less mutations.
None of the newts had a poison level of 10 in the population 200 generations ago, but 50 generations ago, some newts do have a poison level of 10. This change was likely caused by a(n):
Vestigial Structures
Invasive Species
Mutation
Niche
Elephants tusks help them to find food and fight off predators. Over many generations, more elephants have large tusks likely because of:
Natural Selection
Mutation
Extinction
Variation
Based on the data from the histogram, this population of birds likely:
has a soft food source.
has a ton of predators.
has a hard food source.
has very few predators.
Camouflage is a __________ trait because it helps animals to hide from predators.
mutated
vestigial
niche
adaptive
Giraffes have longer necks because of natural selection. Longer necks help them to find food in higher places. These longer necks are considered:
adaptive traits.
non adaptive traits.
vestigial structures.
niches.
Organisms with a non-adaptive trait are more likely to:
thrive in their environment.
reproduce many offspring.
eventually die out.
create many mutations.
What may cause the population of birds to have stronger beaks?
Changes in the environment.
An introduction of a new predator.
A mutation in the population.
All of the Above
More variations in a population give that species a __________ chance of survival.
equal
greater
lower
niche
A population of cactus plants have a variation in the number of needles on their surface. A bird species that eats the cactus has increased in population. A non adaptive trait for the cactus plants is going to be:
low number of needles.
medium number of needles.
high number of needles.
none of the above
