A variation can mean something that is slightly different from similar items of its type (also a variant or variety). It can also apply to a difference itself (e.g. a variat â¦ ion in temperature). In mathematics, variation is the function that compares values among variables.
Cartilage is a type of elastic connective tissue which acts as rubber-like padding to cover and protect the ends of bones at joints. It is a dense matrix of elastic and collagen fibers which are embedded in rubber like ground substance.
Cartilage is a connective tissue whose cells, called chondrocytes, secrete a very specialized matrix. The basophilia of the matrix is due to the GAGs in its ground substance, specifically hyaluronic acid, chondroitin sulfate and keratan sulfate.onnective tissue is the most diverse of the four tissue types with a wide variety of functions. It ranges in consistency from the gel-like softness of areolar connective tissue to the hardness of bone. Blood is also a connective tissue.
