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.

Mosses and ferns differ in their reproductive strategies from gymnosperms and angiosperms in which of the following ways?
In-s [12.5K]

Answer:

The correct answer will be option-A

Explanation:

The Mosses are the non-vascular plants that were developed from the aquatic plants and the ferns are the vascular plants which developed from the bryophytes.

Their life cycle shows alternation of generation and is largely dependent on the water for reproduction mainly fertilization or fusion of gametes.

The male gametes produced in these plant groups are haploid and are released in water which fuses in water with female gamete which is distinct from the higher plant groups gymnosperms and angiosperms where fertilization is mediated by mostly the wind or insects.

Thus, option-A is the correct answer.
