Module 4.2 Information Processing and Transfer

Abigail is conducting research on the nervous system. She has found that an animal's response is coordinated by the central nervous system. Which statement helps Abigail explain how the body reacts to a stimulus?

• Sensory organs are not a part of the nervous system.
• Different sensory receptors can detect different types of stimulus from the environment.
• All animals have the same reaction to a stimulus.
• Peripheral nerves are part of the central nervous system and send messages to the brain.

Cats have a strong sense of smell and rely on it for important activities. How might the cat's sense of smell help it survive?

• The scent of a mouse causing it to hunt.
• The shape of a mouse causing it to hunt.
• The shape of a dog causing it to hunt.
• The scent of a dog causing it to hunt.

Which of the following statements is true about how animals see objects? Select ALL that apply.

• Some animal eyes allow more light in so that an animal can see better in low light.
• Some animals have different structural adaptations that allow them to see differently.
• Visible light reflects off an object and passes through the cornea and pupil on the way to the back of the eye.
