Final answer:
Specialized connective tissues include bone and mucous connective tissue. Bone tissue is dense and hard, providing structure and strength to the body. Mucous connective tissue, found in the umbilical cord of embryos, provides support and cushioning.
Step-by-step explanation:
Specialized connective tissues can be classified as bone and mucous connective tissue. Bone tissue is a dense, hard connective tissue that provides structure and strength to the body. It is characterized by a rigid and calcified matrix. Mucous connective tissue, also known as Wharton's jelly, is an embryonic connective tissue found in the umbilical cord of embryos. It is no longer present after birth and is involved in providing support and cushioning.
