The cartilages are placed horizontally above each other, separated by narrow intervals. They measure about 4 mm in depth and 1 mm in thickness. Their outer surfaces are flattened in a vertical direction, but the internal are convex, the cartilages being thicker in the middle than at the margins.
A synthetic analog is a: synthetically created compound that differs from the Natural compound. Both in it's structure and function. Although probably very similar to the original compound.
Synthetic means that the rubber is made from crude oil, which also happens to be another nonrenewable resource. Nevertheless, the other type (natural rubber) can be harnessed from trees (i.e. rubber tree), in which a substance (latex) is then extracted. Although both are polymers, plastic and rubber differ because: 1. Rubber can be considered elastomers, and thatâs why when compared to plastics, they are naturally more elastic. 2. Synthetic rubber is derived from crude oil, whereas synthetic plastic is made of petroleum and natural gas.
