The FDA has approved the use of these cell lines for the production of these Merck vaccines.. Other common vaccines, including those for chicken pox, hepatitis and rabies, are also propagated in cells originating from legally aborted human fetuses, according to the FDA.erck, the vaccine's manufacturer, acknowledged that those cells were originally obtained from an electively aborted fetus. They were used to start a cell line, which is a cell multiplied over and over again to produce cells that are of a consistent genetic makeup.
Quantum mechanics is the science of the very small. Quantum mechanics explains the behaviour of matter and its interactions with energy on the scale of atoms and subatomic particles. By contrast, classical physics only explains matter and energy on a scale familiar to human experience, including the behaviour of astronomical bodies such as the Moon.
Mechanics is the branch of physics which deals with the motion of material objects under the influence of forces. Mechanics has been divided into two main branches: Classical mechanics and Quantum mechanics. Classical mechanics deals with the laws of motion of physical objects and the forces that cause the motion, while quantum mechanics is the branch of physics which deals with the behaviour of smallest particles i.e., electrons, neutrons and protons.
