Question 1

What is one of the main reasons why the dark-colored rock pocket mice have evolved on lava flows?

Accepted Answer

To match their background and avoid predators

Answer

To signal to other mice

Answer

To blend in with other animals

Answer

To stay cool in the hot environment

Answer

To stand out and attract predators

Question 2

What genetic mutation is responsible for the dark fur color of the rock pocket mice?

Accepted Answer

A difference of four chemical letters in a gene called Mc1r

Answer

A mutation in a gene called Mc2r

Answer

A duplication of a gene called Mc1r

Answer

A deletion of a gene called Mc1r

Answer

An insertion of a gene called Mc1r

Question 3

Which statement best explains why dark-colored rock pocket mice have a competitive advantage on dark lava flows?

Accepted Answer

They are more likely to avoid predators and survive, passing on their genes to future generations.

Answer

They are better camouflaged in their environment

Answer

They have stronger immune systems than light-colored mice

Answer

They are better at finding food sources on dark surfaces

Answer

They can reproduce more frequently than light-colored mice

Question 4

What is the role of natural selection in the evolution of rock pocket mice?

Accepted Answer

It favors advantageous traits that help individuals survive and reproduce in their environment.

Answer

It causes mutations in genes that control fur color

Answer

It determines the color of a mouse's fur based on the environment

Answer

It randomly selects traits for organisms to develop

Answer

It prevents adaptation to new environments

Question 5

How does the process of mutation differ from the process of natural selection in evolution?

Accepted Answer

Mutation is random and occurs throughout DNA, while natural selection is non-random and selects for advantageous traits.

Answer

Mutation leads to extinction of species, while natural selection promotes diversity

Answer

Mutation causes immediate changes in an organism's phenotype, while natural selection occurs over generations

Answer

Mutation is controlled by external factors, while natural selection is controlled by internal factors

Answer

Mutation only affects genes related to fur color, while natural selection affects all genetic traits

Question 6

Why is it important that the genetic changes that make rock pocket mice black are different on different lava flows?

Accepted Answer

It shows that there are multiple genetic ways to adapt to a specific environment and that evolution can occur through different genetic mechanisms.

Answer

It indicates that the mice on different lava flows are unrelated genetically

Answer

It proves that the mice on different lava flows are a different species

Answer

It demonstrates that the mice on different lava flows are identical genetically

Answer

It suggests that the mice from different lava flows have different predators

Question 7

What is the significance of the rock pocket mice evolution in understanding the process of natural selection?

Accepted Answer

It provides a clear example of how natural selection leads to advantageous traits in a population over time.

Answer

It suggests that all organisms will eventually evolve to be the same

Answer

It indicates that mutations are the main driving force behind evolution

Answer

It proves that evolution is driven by random chance alone

Answer

It shows that natural selection has no impact on genetic diversity

Question 8

What is the main reason why dark-colored rock pocket mice have an advantage over light-colored mice on dark lava flows?

Accepted Answer

Dark-colored mice are better camouflaged and less likely to be detected by predators.

Answer

Dark-colored mice have better eyesight and can see predators from far away

Answer

Dark-colored mice have stronger muscles for climbing rocks

Answer

Dark-colored mice can reproduce more quickly than light-colored mice

Answer

Dark-colored mice have a higher body temperature and can withstand extreme heat

Question 9

How does the rock pocket mice example illustrate the concept of evolutionary adaptation?

Accepted Answer

It shows how changes in genes can lead to advantageous traits that help individuals survive and reproduce in their specific environment.

Answer

It suggests that external factors have no influence on the evolution of a species

Answer

It demonstrates how random mutations can shape the evolution of a species over time

Answer

It proves that all organisms will eventually evolve to have the same traits

Answer

It indicates that all organisms have identical genetic mutations for survival

Question 10

What is the key role of natural selection in the evolution of the rock pocket mice population?

Accepted Answer

It acts as a selective force that favors individuals with traits that increase their chances of survival and reproduction in their environment.

Answer

It determines the mating habits of the mice and controls their population size

Answer

It ensures that all mice in the population have the same fur color

Answer

It prevents genetic mutations from occurring in the population over time

Answer

It causes random changes in genes that lead to different fur colors in the mice

Question 11

What does the genetic variation in the rock pocket mice populations on different lava flows suggest about the process of evolution?

Accepted Answer

It demonstrates that evolution can occur through different genetic mechanisms, leading to similar adaptations under similar conditions.

Answer

It suggests that genetic mutations have no impact on the survival of a species

Answer

It indicates that environmental factors are the sole drivers of evolution

Answer

It shows that evolution is a deterministic process with predictable outcomes

Answer

It proves that all populations must have identical genes to survive in their environment
