Low-density lipoprotein. LDL has been associated with the progression of atherosclerosis and blockage of the artery lumen, because it can carry cholesterol into smaller vessels. But LDL is also essential for carrying lipids that keep the human body alive, including in those small vessels. Low-density lipoprotein ( LDL) is one of the ...

Greenhouse gases ( GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. What distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. [1] .

[2] Viscosity is defined scientifically as a force multiplied by a time divided by an area.
