Question

A. Pectin
B. Protein
C. Sugar
D. Both B and C

Answer 1

Hint: Cartilage is a type of connective tissue.
It is composed of collagenous fibers that are closely packed and it also contains chondrin – which is a rubbery gelatinous substance. The main composition is carbohydrates and amino acids.

Complete answer: Cartilage is an important structural component of the skeletal system of the animal body. It is a connective tissue that is softer and more flexible than bone. Cartilage is made up of a special type of cell – chondrocytes.
The solid matrix of fibrous cartilage tissue is made up of proteins and sugars.
The sharks and human embryos are composed of cartilage.
Cartilage is made up of chondroblasts and chondrocytes cells, extracellular matrices.
It is made up of aggrecan, water, and collagen fibers.

So, the correct answer is option D. Both B and C.

Note: The word chondro means the cartilage. Cartilage is of three types - Hyaline cartilage, Elastic cartilage, and Fibrocartilage.
The skeletons of shark and human embryos are made up of cartilage tissue.
The human nose, trachea, and ears are flexible in structure because they are composed of cartilage.
