Aluminium is used extravagantly in the contemporary world, primarily due to its unique structure and desirable properties. Further, aluminium is the most abundant metal in the earth’s crust; thus, scarcity is not a problem. It is a member of the Boron group of chemical elements …
After the ingestion of the alcohol by the man, it passes from the stomach then to the intestines and into the blood stream in a process called absorption. This alcohol is then broken down by body chemicals called enzymes. In this case alcohol is converted …
B. Pertussis is a bacterium that is responsible for causing whooping cough. The symptoms and signs develop as a result of action of the Pertussis toxin on the upper respiratory tract (containing ciliated ciliated pseudostratified columnar epithelium). The individual develops several episodes of uncontrollable coughing. …

Dr. Joseph F. Robare Bad tats are saturated and trans tats. Saturated tats are mostly in meats, dairy products and tropical oils. Saturated fat raises both bad cholesterol and good cholesterol, while trans-fat only raises bad cholesterol. This makes trans fats technically worse than saturated …
Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
