These four species are distantly related and share a common ancestor.
soft cosine or ("soft" similarity)
There are 3 types of muscle tissue: Skeletal (the muscle tissue on bones) Smooth (internal organ make-up) Cardiac (heart)
Both the snowflake and the opaline skeleton of radiolarians appear radially symmetrical, although the radiolarianskeleton is not strictly symmetrical all the way to the center;skeleton's variety is limited by the finite number of species;skeletal symmetry is 3-dimensional, instead of 2-dimensional;skeletal symmetry is not necessarily hexagonal.

Homologous structures refer to structures on different species that are similar in function and their evolutionary origin. Analogous structures are similar in function but do not share a similarity in evolutionary origin.
The skeletal structures are made of an aluminum or steel alloy and its main purpose is to provide support to any new building during construction.

A bone has a multitude of structures that are not visible to the naked eye. The skeletal system of the body is comprised of bone and cartilage, which are made up of millions of microscopic living cells. Each of these structures has a purpose in keeping us on our feet.
