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.
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements. Most stars have small amounts of heavier elements like carbon, nitrogen, oxygen and iron, which were created by stars that existed before them. After a star runs out of fuel, it ejects much of its material back into space. New stars are formed from this material.
