Bones without enough collagen would be ________ than normal bones. Asofter Bmore pliable (flexible) Cmore brittle Dstronger

A group of cells having a similar structure, origin, and function is tissue. Animal tissues can be divided into simple and complex tissue. A tissue made up of one type of cell is called simple tissue. A tissue made up of many types of cells is called complex tissue. Epithelial tissue in animals is simple tissue. Various types of connective tissues are complex tissue.Bones are the connective tissue made up of osteocytes embedded in the solid ground substance. The ground substance is made up of calcium phosphate. The bones form the skeleton of the body. Collagen is the hard insoluble and fibrous protein. The collagen molecules are packed together to form fibrils. Collagen is present in the bone and provides a soft framework to the bone. The collagen present in the bones is type I collagen. Bones without enough collagen would be more brittle than normal bones. A Softer- The hardness of the bones is due to the ground substance calcium phosphate. Collagen is a strong substance and provides elasticity to the bones Hence the absence of collagen will not make bones softer. B more pliable (flexible)- The collagen plays a very important role in giving flexibility to the bones and hence the bones without enough collagen will be less pliable. C more brittle- The absence of collagen reduces the elasticity of the bones. The calcium phosphate provides hardness to the bones. The bones without enough collagen will be more brittle as they will still be hard due to calcium phosphate but can be broken easily. D stronger- Since collagen is a strong substance and provides elasticity to the bones the decrease in collagen will not make bones stronger.
