bio quiz quizizz questions
The Galapagos finches arrived at that island and fairly rapidly evolved into new species. This is an example of:
Adaptive Radiation
Darwin's Theory of Natural Selection says that the number of offspring an organism has ___________________
is more than can survive
When an organism has a trait that makes it resemble another species, either in looks or behavior, we call that ____
mimicry
These cause variations.
mutations
Dark skin color evolved in humans______________
near the equator as a means of maintaining folate levels.
Average phenotypes are favored in the environment, while extremes have lower survival rates.
stabilizing selection
Individuals with intermediate traits are more likely to survive and reproduce
stabilizing selection
A slight difference in an inherited trait between individual members of the same species.
variations
Mutations are a change in what?
DNA
Which of these is an example of natural selection?
Organism that are best suited to an environment tend to survive and reproduce more often.
Whales evolved from land mammals, and lost their ability to walk on land. The change in the shape of their body is an example of :
Physical adaptations.
The ability of pronghorn antelope to lower their body temperature even though they run at very high speeds is likely due to:
Physiological adaptations.
Natural Selection is the ______ Evolution is the ______
Process, Outcome
The theory of evolution by natural selection means that what is changing over time?
The inherited traits of a population.
The coral snake and the king snake look similar to each other. Why?
The king snake mimics the coral snake to attract prey.
In the rock pocket mice, there were two populations of black mice. What evidence showed that they evolved the black fur independently?
The traits evolved on different genes.
With natural selection in place, what will happen to unfavorable traits over time?
They will decrease in frequency through the population.
A physical trait favored by an environmental change can be called an
adaptation
An inherited trait that increases an organism's chance of surviving and reproducing.
adaptation
What is it called when humans decide which traits of an organism are the most desirable and only allow those organisms with the specific, desired traits to breed.
artificial selection
Owls are mostly active during the night time, and therefore do not compete with hawks and other diurnal raptors. This is likely due to:
behavioral adaptations
When an organism has a trait that allows it to blend in with its environment, we call that ____.
camouflage
Over the years, white mice became extinct and darker mice survived. This is
directional selection
individuals with alleles for an extreme type are more likely to survive and reproduce
directional selection
the selection pressure favors the extreme phenotypes, dividing the population into 2 distinct groups
disruptive selection
When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called
evolution by natural selection
Why are advantageous traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
Which of the following explains adaptation.
Beneficial traits allow organism to survive and pass on those traits
