Due to a mutation, some jaguars inherit larger jaw sizes than other jaguars within that population and this trait is passed down from parent to offspring. This gives those jaguars an advantage when it comes to hunting down turtles as prey.
Of the four parts of natural selection, which is this an example of?

Tigers with larger paws hunt deer more easily to survive in an environment where resources are limited. As a result, the tigers with larger paws are “selected” (the larger paws become more common in the next generation of tigers).
Of the four parts of natural selection, which is this an example of?

A beetle’s ability to camouflage (blend in) with a nearby leaf allows it to escape a hungry frog’s appetite.
Of the four parts of natural selection, which is this an example of?

Cheetahs have several adaptations that work well and help them to survive and reproduce in their environment.  They are able to reproduce at a high rate which means more of their genetics and adaptations gets passed on to their offspring.  Cheetahs have a high                               .

What is survival of the fittest?

Various types of cactuses thrive in Arizona’s deserts even though there is little annual rainfall there.  Which adaptation listed below allows all types of cactuses to survive long periods without rainfall?

Male birds of paradise have extremely long, showy tail feathers.  Which of the following statements best describes a selective advantage for having this trait?

A harmless scarlet king snake and a venomous eastern coral snake have similar band patterns, as shown below.  For the scarlet 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 scarlet king snake is to

The antelope jackrabbit lives in a desert environment with limited rainfall, sparse vegetation, and varying temperatures.  When avoiding predators it can reach speeds of up to 45 miles per hour.  The jackrabbit can control blood flow to its large ears, allowing it to adapt to changing environmental stimuli.

Which statement best explains why a jackrabbit’s ability to control blood flow to its ears is important for surviving in a desert environment?

A plant species growing in a certain location has one variety that grows best in wet soil and another variety that grows best in dry soil.  Which outcome is MOST LIKELY to occur at the end of an extended drought at that location?

The survival of a species depends on its ability to adapt to changes in the environment.  A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators.  Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?

The Canyon spotted whiptail and the Sonoran spotted whiptail are lizard species that live in the same desert.  The Canyon spotted whiptail is composed of males and females that reproduce sexually.  The Sonoran spotted whiptail is an all-female species that reproduces asexually.

Which lizard species is more likely to survive a drastic sudden change in climate?

Which of the following describes how a large mouse population with high genetic diversity will most likely be affected by a sudden, significant environmental change?

Scientists estimate that there are more than 20,000 species of ants.  The species range in size from 1 mm long to 38 mm long and live in most environments.  The diets of ants range from flowers and seeds to fluids from their own larvae.  Ants have been able to successfully inhabit so many different environments because their populations have been able to…
