Multiple Choice

True or false?

Individual organisms can make adaptations to better survive and reproduce in their environment.

• True

• False

Multiple Choice

This term refers to the variety of gene combination in a population.

• Genetic Variation

• Adaptations

• Natural Selection

• Favorable Traits

Multiple Choice

This is a process in which the organisms with favorable traits survive and reproduce more often than those without, making the favorable traits more common in the population.

• Genetic Variation

• Adaptations

• Natural Selection

• Favorable Traits

Multiple Choice

True or false?

Two different species can mate and create genetic variations that may be beneficial to the new organism's survival. This is called adaptation.

• True

• False

Multiple Choice

True or false?

Adaptations must occur over multiple generations.

• True

• False

Multiple Choice

The forest the peppered moths live in is populated with light birch trees.

What is the favorable trait for moths living here?

• Light wings

• Dark wings

Multiple Choice

Can human activity influence natural selection?

• Yes

• No

Why did moth color change over time?

.

Scientists suspect the Industrial Revolution is to blame.

.

Why would moth color change due to the Industrial Revolution?

Lichen (type of tree fungi) cause tree bark to appear lighter.

.

Pollution can cause lichen to die, resulting in tree bark appearing dark.

.

Why is this important?

Multiple Choice

Why did scientists find that light ornamentation of dragonfly wings was the favorable trait in warmer environment?

• Light wings help them fly faster.

• Dark wings overheat.

• Light wings signal mates better.

• Dark wings are more noticeable by predators.

Multiple Choice

Why did the study find that ornamentation of

female dragonflies did not change with climate?

• Female dragonflies don't need to signal mates with ornamentation.

• Female dragonflies spend more time in the shade looking for food.

• Female dragonflies do not have wings.

• Female dragonflies are built to regulate temperature better than males.
