Question

Which of the following statement is incorrect?
(1) The interellular material of cartilage is solid and
pliable and resists compression
(2) All the cartilages in vertebrate embryo are
replaced by bones in adults
(3) Cartilage is present in the tip of nose, outer ear​

Answer 1

Answer:

All of them are correct

Explanation:

1st option

The intercellular matrix is solid while cartilage is pliable due to the presence of chondroitin salt. Chondroitin is a sulfate salt that provides resistance to the compression and is responsible for bending or flexibility. So option 1 os correct.

2nd option

Cartilage is a soft skeletal tissue. It is not rigid like bone. It is found more abundantly in vertebrate embryos because most of the bones forming skeleton of the adult are cartilaginous in the early stage. So option 2 is correct.

3rd option

There are mainly three different types of cartilage namely Hyaline, elastic and fibrous. ... The type of cartilage present at the tip of the nose is Hyaline Cartilage. Elastic cartilage is found in the external or outer part of the ear. It has moderate elasticity. So option 3 is correct.

All the option are correct

Hope it helps...
