Statins are a group of medicines that can help lower the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is often referred to as bad cholesterol, and statins reduce the production of it inside the liver.aving a high level of LDL cholesterol is potentially dangerous, as it can lead to a hardening and narrowing of the arteries (atherosclerosis) and cardiovascular disease (CVD) . CVD is a general term that describes a disease of the heart or blood vessels. It is the most common cause of death in the UK.
The colour of a star is primarily a function of its effective temperature. You should recall that a star approximates the behaviour of a black body radiator. As a black body gets hotter its colour changes. If you were to heat a solid shot put it would first emit radiation in the infrared region.
The density, temperature and pressure of the gas increase from the outside towards the center of the star. At each point within the star, the pressure of the gas is proportional to the weight of the upper layers. Stars have a noticeable color and it's by a star's color that we are able to calculate its temperature. Stars differ in color ranging from blue-white to red. These stellar colors can be measured by several methods. The most commonly used method is the use of a photoelectric photometer, which can measure stellar colors with the aid of filters.
