The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided, and determine their validity. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Intervertebral discs are tougher and stronger than the pinna of man." - Intervertebral discs are located between the vertebrae in the spine and serve as shock absorbers, providing strength and flexibility to the spinal column. 2. **Understanding the Reason**: - The reason states that "Intervertebral discs are formed of fibrocartilages while the pinna is made of calcified cartilage." - Intervertebral discs consist of two main parts: the annulus fibrosus (outer layer) and the nucleus pulposus (inner gel-like core). They are primarily made of fibrocartilage, which is known for its toughness and ability to withstand pressure. - The pinna (the outer part of the ear) is primarily made of elastic cartilage, not calcified cartilage. Elastic cartilage provides flexibility and shape but is not as strong as fibrocartilage. 3. **Evaluating the Truth of the Statements**: - The assertion is true: Intervertebral discs are indeed tougher and stronger than the pinna. - The reason is false: The pinna is made of elastic cartilage, not calcified cartilage. 4. **Conclusion**: - Since the assertion is true and the reason is false, the correct answer is that the assertion is true but the reason is false. ### Final Answer: - The correct option is: **Assertion is true but Reason is false.** ---

Why are inte-rvertebral discs considered to be the strongest form of cartilages?

Assertion :- Calcified cartilage is the strongest cartilage. Reason :- Calcified cartilage is the srongest cartilage. Calcified cartilage is formed by the calcification of elastic cartilage.

Assertion : Calcified cartilage is formed by the calcification of hyaline cartilage. Reason : Calcified cartilage is the strongest cartiage.

Assertion: Cardiac muscles have striations and fiber is nucleated and involuntary. Reason: Intercalated disc form the three-dimensional network of cardiac muscle fiber.

Assertion:- Images formed by TIR (Total internal reflection) are much brighter than formed by mirrors or lenses. Reason:- IN TIR, there is no loss of intensity while in case of reflection from mirrors or refraction from plane surfaces or lenses there is some loss of intensity as all light can never be reflected or refracted.

Assertion: Pectoral girdle articulates the with the axial skeleton while pelvic girdle articulates the upper limbs with the axiel skeleton. Reason: The two halves of the pelvic girdle meet ventrally to form the pubic symphysis containing hyaline cartilage.

Assertion : A ring and a disc of same mass and radius begin to roll without slipping from the top of an inclined surface at t=0 . The ring reaches the bottom of incline in time t_(1) while the disc reaches the bottom in time t_(2) , then t_(1) lt t_(2) Reason : Disc will roll down tha plane with more acceleration because of its lesser value of moment of inertia.
