Answer 1

Answer:

Cartilage is an important structural component of the body. It is a firm tissue but is softer and much more flexible than bone. Cartilage is a connective tissue found in many areas of the body including joints between bones e.g., the elbows, knees, and ankles. Cartilages are not rigid connective tissues, but soft and flexible. But, it is true in the case of bones. A bone is a rigid organ that constitutes part of the vertebral skeleton. Bones support and protect the various organs of the body, produce red and white blood cells, store minerals and also enable mobility. Bone tissue is a type of dense connective tissue.  Blood is considered a connective tissue because it has a matrix.
