What is the primary role of sensory receptors in complex animals?

• To generate motor responses directly

• To integrate sensory input before directing motor responses

• To regulate the production of hormones

• To stimulate the growth of sensory organs

Which of the following sensory receptors respond to chemical molecules?

• Photoreceptors

• Mechanoreceptors

• Chemoreceptors

• Thermoreceptors

Sensory adaptation refers to:

• An increase in response to a stimulus over time

• A decrease in response to a continuous stimulus

• The transformation of stimuli into nerve impulses

• The brain’s ability to recognize different stimuli

What happens when photoreceptors in the eye are stimulated by pressure instead of light?

• The person perceives pain

• The brain interprets the sensation as sound

• The person sees 'stars' or visual patterns

• The eye stops functioning temporarily

Which part of the human body contains olfactory receptor cells?

• Tongue

• Ears

• Nose

• Skin

What is the umami taste associated with?

• Salts and sugars

• Spicy foods

• Foods rich in amino acids like MSG

• Sour and bitter flavors

The lateral line system in fish is primarily used for:

• Detecting sound waves

• Locating other fish and detecting movement in water

• Maintaining body temperature

• Filtering oxygen from water

What structure in the human ear is responsible for amplifying sound?

• Cochlea

• Semicircular canals

• Ossicles (tiny bones in the middle ear)

• Tympanic membrane

Which part of the inner ear is responsible for detecting rotational equilibrium?

• Cochlea

• Semicircular canals

• Utricle

• Saccule

Which component of the human eye is primarily responsible for focusing light onto photoreceptors?

• Retina

• Iris

• Cornea and lens

• Optic nerve
