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 Rubber. Synthetic rubber is made from petroleum. This latter substance is natural, as is latex, but rubber producers put the petroleum through a process known as polymerization. This process creates long chains of molecules called polymers. These polymers are designed to resist weathering. They do not break down anywhere nearly as fast as natural latex.
