Biology Essentials: Behavior and Natural Selection

What was a significant limitation in Darwin's study of natural selection?

• He ignored the concept of evolution.

• He focused too much on plant life.

• He lacked genetic and mathematical data.

• He did not consider the role of behavior.

Which of the following is an example of innate behavior?

• A dog learning to fetch.

• A baby chimpanzee's grabbing reflex.

• A chimpanzee using a tool.

• A bird learning to sing.

What is phototropism?

• Growth in response to light.

• Growth in response to sound.

• Growth in response to temperature.

• Growth in response to water.

How does phototropism benefit plants in a forest?

• It allows them to grow taller than other plants.

• It makes them more resistant to diseases.

• It enables them to capture more light.

• It helps them conserve water.

What does photoperiodism help plants determine?

• The best time to flower.

• The best time to shed leaves.

• The best time to grow roots.

• The best time to produce fruit.

Why is the timing of flowering crucial for plants?

• It influences their pollination success.

• It impacts their root growth.

• It determines their water intake.

• It affects their ability to photosynthesize.

What is the primary purpose of a bowerbird's bower?

• To store food.

• To protect from predators.

• To attract a mate.

• To shelter from rain.

How does a female bowerbird choose a mate?

• By the quality of his bower.

• By the sound of his call.

• By the color of his feathers.

• By the size of his territory.

What is coevolution in the context of pollination?

• Insects evolving to avoid plants.

• Plants evolving to resist insects.

• Plants and insects evolving together.

• Plants and insects evolving independently.

What did Darwin predict about the orchid in Madagascar?

• It would have a short stem.

• It would be pollinated by a long-proboscis moth.

• It would grow in cold climates.

• It would attract many birds.
