The ability to visualize or differentially identify microscopic structures is frequently enhanced through the use of histological stains. Histology is an essential tool of biology and medicine. The study of tissues bridges the gap between cell/molecular and organismal biology. In animals there are four major tissue types: Epithelial, Connective, Muscle, and Nervous tissues. Each tissue is classified based on the location, shape, and function of the cells which comprise them.
A synthetic lubricant contains more highly refined base oils than those used in conventional mineral oils, offering you superior protection and performance. Synthetic engine oils provide a variety of benefits that keep your engine running at optimal performance for years.
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.
