Which refers the process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations?

• camouflage

• natural selection

• variation

Individuals within a population have slightly different traits, called variations. How do variations improve the likelihood that a population will survive?

• Variation enables individuals to produce offspring that will survive into adulthood.

• Variation enables the population to create new genes, which help individuals survive a significant change in their environment.

• Variation provides the raw material upon which natural selection acts in a population.

Rainfall in a tropical region has been below average for 10 consecutive years. Insect species adapted to dry conditions are much more plentiful at the end of the 10 years. Which of the following statements best explains the increase in the population of these insects?

• Biodiversity in the region has increased due to the dry conditions.

• Insects with a high tolerance for dry conditions have moved out of the region.

• Natural selection has favored insect species with high tolerance for dry conditions.

• Natural selection has selected against insect species that are adapted for dry conditions.

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 more effective at finding mates than other fish.

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

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

• 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 plants change over time

• that ferns stopped evolving 25 million years ago

• that only animals evolve

When has speciation occurred?

• When populations no longer look the same
• When populations no longer have the same frequency of alleles
• When populations are living in different environments
• When populations can no longer interbreed
