Humans rely on sensory receptors to interpret messages about their surroundings. Sensory receptors respond to mechanical, physical, or chemical stimuli. There are different kinds of sensory receptors for detecting different kinds of stimuli. Chemoreceptors are specialized nerve cells that pick up chemical stimuli, such as smells or the pH level of foods. Such stimuli tell the brain and body to react a certain way to protect the body. If a person in a controlled test is introduced to a safe chemical stimulus, what is the most logical prediction you could make? A. The person will bat the eyelids to push the chemicals away with the eyelashes.
B. The person will plug the nose to shield the body from offensive chemical smells.
C. The person will cover the ears to protect the ears from chemicals in loud noises.
D. The person will bite the nails to keep the chemical from seeping into the fingers.
