Multiple Choice

What is Evolution?

• Time over change

• Evolving from monkeys (NO)

• Change over time

• I dont know

Multiple Choice

Who is the father of evolution?

• Charles Darwin

• Gregor Mendel

• Isaac Newton

• Albert Einstein

Multiple Choice

What is another name for natural selection?

• survival of the smartest
• survival of the fastest
• survival of the biggest
• survival of the fittest

Multiple Choice

A change in a DNA sequence that affects genetic information

• mutation

• fitness

• transformation

Multiple Choice

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

Multiple Choice

An inherited characteristic that increases an organism's chance of survival

• adaptation

• evolution

• fitness

Multiple Choice

Which of the following ideas is supported by Darwin’s observation of local variation among tortoises in the Galápagos Islands? 

• artificial selection
• adaptation
• acquired characteristics
• tendency towards perfection

Multiple Choice

The harmless King snake and the venomous Coral snake have similiar band patterns. For the king snake, the adaptation of having a banding pattern like the eastern coral snake's is known as mimicry. The outcome of this adaptation in the king snake is to-

• Make it easier for the scarlet king snake to attract prey

• Make it easier for the king snake to interbreed with the other snake

• Allow the scarlet king snake to blend in with its environment

• Protect the scarlet king snake from predators

Multiple Choice

Certain insects resemble the the bark of the trees on which they live. Which statement provides the best explanation for this resemblance?

• The lack of mutations resulted in the protective coloration

• The insects needed camouflage so they developed protective coloration

• The trees caused mutations in the insects that resulted in this protective coloration

• Natural selection played a role in the development of this protective coloration

Multiple Choice

When looking at two birds of the same species, you notice that one has darker feathers than the other one. You also notice that one has a beak that is just a little longer. These slight differences within members of the same species are called.....

• Fossils

• Extinction

• Meiosis

• Variations

Multiple Choice

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

Multiple Choice

What characteristic did Darwin observe about the finches on the Galapagos Islands?

• Their feathers 
• Genotypes 
• Their beaks
• Their body sizes

Multiple Choice

What happens to new traits that HELP organisms survive over time?

• They become MORE COMMON

• They become LESS COMMON

• They are EQUALLY COMMON

Multiple Choice

Which of the following best characterizes natural selection?

• Only giraffs with long necks move to an area with tall trees

• The necks of giraffes that did not leaves from the top of the trees grew shorter necks from not using them

• Giraffes with long necks were able to survive better in an environment where leaves only grew at the tops of the trees

• Leaves only grow on the tops of trees so giraffes responded by growing their necks

Multiple Choice

What is reproductive success?

• A: The ability to produce healthy offspring that survive.

• B: The ability to reproduce.

• C: The ability to find a mate.

• D: The ability to not reproduce.

Explanation Slide...

Reproductive success is the ability to produce healthy offspring.

Multiple Choice

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce?

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetime

• Some individuals tend to produce fewer offspring than others in the same environment

• Some individuals are better adapted to their environments than others

• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes

Multiple Choice

What is the term for a feature that allows an organism to survive better in its environemtn?

• variation

• adaptation

• homologous structure

• vestigial structure

Multiple Choice

Jaguars with slightly larger jaws and teeth are better able to eat shelled reptiles in addition to mammals. These Jaguars are likely to survive longer and leave more offspring than jaguars that eat only mammals. Which scientific concept explains how large jaws and teeth become typical characteristics of jaguars?

• Natural selection

• Artificial selection

• Asexual Reproduction

• Biogeography
