The shape of the external ear is maintained by ________. Select one: a. hyaline cartilage b. adipose tissue c. fibrocartilage d.
d1i1m1o1n [39]

Answer:

D) elastic cartilage

Explanation:

Cartilage is a connective tissue which is fibrous in composition which provides its physical properties like the softness, elasticity and strength.

There are three types of cartilages- the elastic, hyaline and the fibrocartilage. Among these three the cartilage which forms the external ear is the elastic cartilage. The elastic cartilage is composed of the elastin protein, type II collagen and the elastic fibres. The presence of the elastin proteins and fibres allows the ear to be an elastic organ.

Thus, Option-D is the correct answer.

Positive control is Ginger root (should indicate the presence of amylase)

Negative control is Cellulose (should not contain amylase)

Here the presence of amylase is tested by testing the presence of starch using an IKI solution. Saliva is included in this experiment because it contains the enzyme amylase.
