Question 30

Which sense organ is primarily responsible for vision?

Answer 30

The eyes.

Question 31

What type of receptors do our noses use to detect smell?

Answer 31

Olfactory receptors.

Question 32

How does the ear contribute to both hearing and balance?

Answer 32

The ear contains structures (cochlea for hearing and vestibular system for balance) that process sound and maintain equilibrium.

Question 33

What part of the eye adjusts the amount of light that enters?

Answer 33

The iris

Question 34

Which sense organ contains taste buds?

Answer 34

The Tongue

Question 35

What is the function of the skin as a sense organ?

Answer 35

The skin detects touch, temperature, pressure, and pain.

Question 36

What is the role of photoreceptors in the eye?

Answer 36

Photoreceptors (rods and cones) convert light into neural signals for vision.

Question 37

How do we perceive sound vibrations through our ears?

Answer 37

Sound vibrations cause the eardrum to vibrate, which is transmitted through the ossicles to the cochlea, where hair cells convert them into neural signals.

Question 38

What sense organ is most directly involved in detecting temperature and pressure?

Answer 38

The skin

Question 39

Suspensory ligaments

Answer 39

A ring that maintaining and supporting the position of the eyeball

-Color blindness -Photokeratitis -Retinitis pigmentosa -Usher syndrome

Question 42

Focusing on a distant object:

Answer 42

-Light rays diverging only slightly -The thin lens refracts the light rays slightly -The cornea refracts the light rays

Question 42

Focusing on a nearby object:

Answer 42

-Light rays diverging greatly -The thick lens refracts the light rays greatly -The cornea refracts the light rays

Question 43
