Multiple Choice

What is evolution?

• Staying the same

• Change over time

• Genetics skip generations

Multiple Choice

This picture shows....

• how we are NOT all related

• how we are all related to a common ancestor

Multiple Choice

What is biodiversity?

• The study of biological species in a laboratory

• The variety of life on Earth, encompassing variations in genetics, species, and ecosystems

• The study of the human species exclusively

• The study of marine life forms only

Multiple Choice

What is evolution?

• The process through which species remain unchanged over time

• The process through which species change over time due to variations in traits that are heritable

• The process through which species adapt to other species

• The process through which species communicate

Multiple Choice

What is Darwin famous for studying?

• Penguins

• Beagles

• Fishes

• Finches

Multiple Choice

Which set of Islands had a strong influence on Darwins ideas?

• Hawaii

• Galapagos

• Samoa

• Florida Keys

Open Ended

What was incorrect about the previous slide?

Multiple Choice

Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest.

• Extinction
• Speciation
• Natural Selection
• Artificial Selection

Multiple Choice

Natural selection explains HOW organisms change over time. What is the process in which populations are changed over time?

• Digestion

• Elimination

• Evolution

• Adaptation

Multiple Choice

Another term for Natural Selection is:

• Breeding

• Commensulism

• Communism

• Survival of the fittest

Multiple Choice

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype

Multiple Choice

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Multiple Choice

Why is the mouse population changing over time? (You can enlarge the picture by placing your cursor on it.)

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Multiple Choice

Which organisms are most likely to survive?

• the best adapted (best fit)

• the fastest

• the strongest

• the most domesticated (tamed)

Multiple Choice

According to natural selection, light colored tree trunks would favor ___________________________.

• light colored moths

• dark colored moths

• red colored moths

• red and light colored moths

Multiple Choice

Why are advantageous (better fit) traits more likely to be passed onto offspring?

• They are more likely to survive and reproduce.

• They are more likely to die and not reproduce.

• They are able to reproduce more offspring.

Multiple Choice

A slight difference in an inherited trait between individual members of the same species. (Example: Some rabbits have white fur and some have black fur.)

• variations

• adapatations

• homologous structures

• analogous structures

Multiple Choice

The passing of genetic traits (DNA) from parent to offspring is __________.

• Survival of the fittest

• Heredity

• Evolution

Multiple Choice

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth

• Light moth

• Both will be equally successful

• Neither will be successful

Multiple Select

Which trait(s) would be considered an adaptation for a moth? (Check all that apply.)

• Flies very slow.

• Wings camouflaged within its environment

• The catepillar stage camouflages within its environment.

• Flies very fast.

Multiple Choice

A grizzly bear survives because he is well-adapted (best fit) to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

Multiple Choice

Predict which moth would increase in population over time.

• light colored

• dark colored

Multiple Choice

What is the best claim for this image?

• The grey wolves are best adapted to the Arctic

• The brown rabbits are best adapted to the Arctic.

• The white rabbits are best adapted to the Arctic.

Multiple Choice

If Easter eggs were living species of organisms, their different colors would be considered:

• Adaptations

• Variations

• Different species

• Extinct species

Multiple Choice

The peppered moth's color camouflaged it on the light colored tree bark. It's color was an example of a/n

• Variation

• Dominant trait

• Recessive trait

• Adaptation

Multiple Choice

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 trait is an acquired phenotype.

Multiple Choice

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype

Multiple Choice

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation
