Which is not an example of an adaptation?

A cat sleeps on the sofa to avoid the vacuum cleaner.

A bird's beak allows it to crack open hard nuts.

A zebra's stripes allow it to confuse its predators.

A frog's large hind legs allow it to jump from danger.

Change over time in a population.

Negative traits are acquired in populations.

The theory of evolution by natural selection means that what is changing over time?

The inherited traits of a population.

The acquired traits of a population.

According to the theory of natural selection, some individuals are more likely than others to survive and reproduce because they:

are better adapted to their environment than others and will pass on those adaptations to future offspring.

pass on to their offspring their newly acquired traits.

do not pass on newly acquired traits.

produce fewer offspring than others in the same environment.

Darwin observed 13 species of finches on the Galapagos Islands. What did Darwin conclude about the finches?

They evolved from a common ancestor.

They all came from different continents.

they evolved from 13 different types of birds.

they developed from other types of organisms.

Which of the following correctly lists the four essential parts of natural selection?

overproduction of offspring; genetic variation; struggle to survive; successful reproduction

selection; underproduction of offspring; homeostatsis; fossil records

underproduction of offspring; genetic variation; extinction; adaptation

adaptation; inconsistency; sexual reproduction; energy use

According to the theory of natural selection, what would happen to a species of lizards when a new predator is introduced into the environment where the lizards live?

The lizards that already have the traits needed to avoid the new predator would be more likely to survive and reproduce, and the ones that do not would be less likely to survive and reproduce.

All of the lizards would try to develop new traits to avoid the new predator.

Some of the lizards would try to develop new traits to avoid the new predator, and the other lizards would die.

Because all lizards of the same species have the same traits, one lizard would not have an advantage over another lizard. They would either all survive or all die.

Which of the following is NOT part of the process of natural selection?

Members of the same species compete with one another for resources.

Variation exists among individuals in a species

Traits are inherited from one generation to the next.

Some variation must be present in a population in order for natural selection to take place. These variations arise from mutations in the DNA and:

sorting of chromosomes during sexual reproduction

combining of chromosomes during organ development

removal of chromosomes during selective breeding

changing of chromosomes during cloning

Which of the following statements best describes a "selective pressure?"

An external factor which affects an organism’s ability to survive in a given environment

The organisms DNA which affect the organism’s ability to survive in a given environment

The distance a bird can fly and how this affects it’s ability to survive in a given environment

An adaptation that affects an organisms ability to survive in a given environment

Based on the picture and what you know about natural selection, which mice are most likely to increase in number in this environment?

they will both increase the same amount

Variation happens as a result of the exchange of genetic information as it is passed fromparent to offspring.Which of the following is true about inherited variation?

Variation can influence whether organisms are more likely to survive to reproduce.

Variation can influence the resources that are available to an organism.

Variation can influence the amount of rainfall in an ecosystem

Variation can influence the amount of available food in an ecosystem

Why is the mouse population changing over time?

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

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 dark mice than light mice because they can see the dark mice more easily

What statement is true regarding why natural selection can be easily seen in insects and bacteria?

Insects and bacteria can reproduce faster than more complex organisms and pass on selected traits quicker

Natural selection only occurs in prokaryotic cells

Insects were the first multi-cellular organism to live on land

Bacteria have directly evolved from insect traits.

Some mammals such as Moose, Deer, and Water Buffalos have defensive adaptations such as horns or antlers to fight predators. Males also use them to fight other males during mating season. Select the choice that correctly describes the adaptations described in the narrative above.

The antlers and horns are structural adaptations, and the fighting is a behavioral adaptation.

These mammals are carnivores that use their antlers to attack and kill their prey.

Antlers are examples of behavioral adaptations used by Moose and Deer

Deer and Moose antlers are structural adaptations, but horns are not.

The graph above shows the variation in the deer population in the Kaibab Plateau from 1905 to 1939. Between 1907 and 1923, the natural predators of deer were eliminated from the area by hunters. What was the most likely reason for the decline in the deer population after 1924?

The increased number of deer led to increased competition for resources.

The deer stopped competing for resources because they had no predators.

A large number of deer left the region in search of new predators.

The removal of predators caused fewer resources to be available to the deer.

Which best describes the role of mutations in natural selection?

A mutation may result in an adaptive trait that makes an organism more likely to survive and reproduce

Mutations help an organism to better survive in their environment

An organism may acquire a helpful mutation by interacting with the environment

Organisms with certain traits are more likely to win competitions for mutations

Why is competition important for natural selection?

It shows which variations are more successful, allowing the organisms with those variations to survive.

It causes organisms, regardless of which traits they have, to die out, reducing the population size.

It causes organisms to get stronger due to having to outcompete other species.

Competition is not important for natural selection.

The theory of evolution by natural selection means that what is changing over time?

The inherited traits of a population.

The acquired traits of a population.
