In meteorology, the term isotherm refers to a contour line that connects points on a weather map that have equal temperatures at a given time. Just as contour lines on topographical maps are used to show gradients of elevation, isotherms are used to show gradients of temperature. Isotherms usually are shown in five- or 10-degree intervals on maps. The temperature differences they delineate are often indicated by different colors. The curve of an isotherm is shaped by variations in temperature across the area being mapped.
Biotin is vital to cell proliferation, which is why it is a valuable tool in hair growth. When ingested, biotin reacts with cell enzymes and plays a vital part in producing amino acids, which are the building blocks of protein.
Biotin for Hair Growth. Biotin, also referred to as vitamin H, is a type of B complex vitamin that occurs naturally in a variety of common foods. The optimum amount of biotin aids in the metabolization of fatty acids and amino acids. Research also suggests its role in stabilization of blood sugar levels.
