9. Animals are able to sense sounds in their environment because they have

• Each kind of sound triggers a different cell in the inner ear.

• Sound waves enter the brain through openings in the skull.

• Receptors pick up the information about sound waves and send it to the brain.

• The ears send signals out into the environment and interpret what comes back.

Different sensory receptors are located in different parts of the body; sensory receptors in the eyes are specialized for detecting light. Which one is a concise statement about them?

• Sense receptors in the eyes need to be larger than other kinds of receptors.

• Sense receptors in the eyes need to be sensitive to changes in the light

• Sense receptors in the eyes need to be able to send information to the muscles.

• Sense receptors in the eyes need to be faster at processing information.
