Two organisms that are closely related would have

completely different DNA sequence

The diagram represents the relationship between beak structure and food in several species of finches found on the Galapagos Islands. The different beak structures observed in the diagram are evidence of

different species of finches adapting to different environments over many generations

finches changing their beak characteristics so that they could feed efficiently

finch species with different beak structures coming to the Galapagos Islands from the mainland

finches mating with birds of other species and acquiring some of their traits

Natural selection is best described as

differences in survival rates as a result of different inherited characteristics

a change in an organism in response to a need of that organism

a process of nearly constant improvement that leads to an organism that is nearly perfect

inheritance of characteristics acquired during the life of an organism

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

A population of mice, some with light-colored fur and some with dark-colored fur, is introduced into a field with dark soil. A few generations later, the majority of the mice have dark-colored fur. Which of the following best explains this change?

Dark-colored mice can hide easier from predators.

Light-colored mice can run faster.

Dark-colored mice have fewer offspring.

Light-colored mice have changed color over generations.

What most likely caused the finches on the Galapagos Islands to have beaks that were different from the finches on the mainland?

There were different types of food available on the island.

There were different types of predators on the island.

The finches had no water to drink.

The finches on the mainland could not fly high enough.

A mutation is defined as:

A change in the cell's structure

Anything that changes in an embryo

Any change in the physical features of a human

The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?

Fossil D is older than fossil C

Fossil A and C are the same age

Fossil B is older than fossil C

Fossils A is older than fossil B

WHY is this variation is best for survival?

fur color that blends in to it's environment

How will this mice population most likely change in the future?

The white mice will go extinct.

All of the mice will grow longer fur.

All of the mice will grow longer claws.

The longnose butterfly fish has a dark spot near its tail that looks like an eye. Its "eyespot" makes predators think they are attacking the head rather than the tail. Why does the longnose butterfly fish have an evolutionary advantage over other fish?

It is likely to produce more offspring that survive to maturity.

It is more effective at finding mates than other fish.

It is more effective at catching shrimp and worms than other fish.

It uses less energy to swim than other fish.

If scientists were to compare the fossil of a fern that lived millions of years ago with other fern fossils that were formed later, what would they most likely find?

that plants had bones millions of years ago

that ferns stopped evolving 25 million years ago

How would a warming climate affect the species in an ecosystem?

individuals best able to survive the heat would become more likely to reproduce

individuals might die off but a species cannot disappear completely

species would increase in number to offset the numbers killed by the heat

species that have never been seen before would suddenly appear

The diagram below shows a portion of the fossil record in sedimentary rock. Different rock layers and fossils are clearly visible.

Layer A contains the most recently formed fossils.

Layer B contains the second-oldest fossils.

The fossils in layer B are older than those in layer D.

The praying mantis has few predators. Yet it is adapted to look just like the twigs and small branches where it is usually found. Explain how this adaptation helps the praying mantis survive.

It hides better in its environment to be a better predator.

It hides better in its environmet to be harder prey to find.

It eats twigs and you are what you eat.

What conclusion can be drawn from the diagram to the right about Troodontidae and Oviraptorosauria?

They all share the common ancestor Archaeopteryx.

They all share the common ancestor Dromaeosauridae.

They have all of the same traits in common with Archaeopteryx.

There were no evolutionary changes between these two species.

Look at the diagram to the right. Which species will have the greatest physical difference from its ancestor the Drosophila melanogaster? Explain how you determined your answer.

Drosophilia equinoxalis caribbensis

Drosophilia equinoxialis equinoxialis

The diagram shows the beaks of four Finches that developed over time from one parent species. Explain why the beak shape of each species of Finch developed differently.

They adapted to better eat the different foods available to them in the region they live in.

They adapted to look better, so they could reproduce and pass on traits.

Their beaks adapted to help them hide from predators.

They adapted so they could smell better.

Which of the following most likely supports how giraffes evolved long necks?

More long-necked giraffes survived to pass on their genes.

More short-necked giraffes survived to pass on their genes.

Short-necked giraffes grew longer necks to reach higher leaves.

Short-necked giraffes modified their diets to evolve into a new species.

The walking catfish is a species of fish that walks on land using its pectoral fins. During drought conditions, when there is little water in its habitat, the walking catfish can use its pectoral fins to get to areas with water.

Walking catfish with large pectoral fins are more likely to survive a trip to distant areas of water. The population is likely to evolve to have larger pectoral fins.

Walking catfish with small pectoral fins are more likely to survive a trip to distant areas of water. The population is likely to evolve to have smaller pectoral fins.

Walking catfish with large pectoral fins and those with small pectoral fins are equally likely to survive a trip to distant areas of water. Both types of catfish will then become extinct.

Walking catfish with large pectoral fins and those with small pectoral fins are equally likely to not survive the trip to distant areas of water. Both types of catfish will then become extinct.
