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.

Answer:

Th correct answer is A. Capsid

Explanation:

T-2 phage is a bacteriophage which is virulent to E.coli which means T2 phage infects E.coli. The genetic material of T2 phage is linear DNA which is double-stranded. The genetic material of T2 phage is enclosed in a protein coat which is called capsid.

This capsid protects the genetic material of bacteriophage by any enzymatic digestion, helps the virus to attach the host cell and helps the virion to penetrate the cell membrane of the host cell and inject its genetic material in the host cell. Therefore capsid is the correct answer.
