Q

A layer of fat which aids in insulation

A

Hypodermis

17
Q

Made up of pinna and auditory canal

A

Outer ear

18
Q

It traps the sound waves and direct them to the eardrum which is part of the middle ear

A

Pinna

19
Q

Smaller chamber; has circulatory functions. It carries nutrients and oxygen ti the different parts of the eye and collects wastes

A

Aqueous Humor

20
Q

Mucus membrane on the surface of the eye, lining the back of the eyelid and the white of the eye to keep them moist

A

Conjunctiva

21
Q

Squids have a (hard, soft) lens which can move back and forth when focusing

A

Hard

22
Q

Human eye have (hard, soft) lens hence, it can be changed when focusing

A

Soft

23
Q

In Human eye, what happens to the lens when looking at near objects?

A

They become round and thick which enables light from the object to focus

24
Q

What happens to the lens of the eye when focusing on a far object?

A

Flat and thinner

25
Q

It is lined with sensory receptors located at the tip of the cillia

A

Nasal cavity

26
Q

Are evolved epithelial cells that become sensory cells

A

Taste buds

27
Q

Which sensory receptors will detect music?

A

Mechanoreceptors

28
Q

Why is the skin made up of several layers of cells?

A

The bottom layer replaces the top layer

29
Q

Which is not found in the dermis

A

Fat layer

30
Q

The correct sequence of the parts of the ear where sound passes

A

Outer ear -> eardrum -> cochlea -> Organ of Corti

31
Q

Which part of the ear is responsible for maintaining balance?

A

Semicircular canals

32
Q

Which light detecting structures is NOT capable of forming images?

A

Eye cup

33
Q

Which of the following organisms have compound eyes?

Flatware, squids, insects, humans

A

Insects

34
Q

The lens of the human eyes is controlled and attached to ligaments. What do you think will happen if these ligaments stop working?

A

The lens will not be able to focus on either near or far objects

35
Q

Which part of the human eye has the highest concentration of photoreceptors?

A

Fovea

36
Q
