1. Prehistoric Times - Beginning of the Christian Era (Black Magic) Existence of Fire Arguably the first chemical reaction used in a controlled manner was fire. However‚ for millennia fire was simply a mystical force that could transform one substance into another while producing heat and light. Fire affected many aspects of early societies.

Biochemistry: categories of organic compounds Ruddy Severino There are four major compounds that compose the human body. It is impossible that anything living on earth today can live out these organic compounds. Those compounds are carbohydrates‚ lipids‚ proteins‚ and nucleotides. Each compound has a major important function that is essential to the human body as well as other living organisms on earth. Carbohydrates serve as the main source of energy. Carbohydrates contain carbon‚ hydrogen

Scientists believe that in order to successfully look for extraterrestrial life we must first look for water because based on what we know about life and biochemistry‚ it’s likely that the alien biochemistry will need a solvent (like water) and one or more elemental (like carbon) to be able to function successfully. We also Believe that if we are looking for any type of life on other planets we should first be looking for microbes

abnormality is the biological model this is also known as the medical model and assumes that abnormal behaviour is as a result of a physical problem. This should be treated medically by either medication or surgery. It is focused on the genetics‚ biochemistry‚ neuroanatomy and infections.

Copernican Heliocentrism impact to Modern Science Michael White WGU February 24‚ 2011 Thesis Statement: Nicolas Copernicus Heliocentrism helped to revolutionize science and catapult man into space. Introduction: Early science and astronomers believed the earth to be the center of the universe; this was known as the Geocentric Model. Prior to the 17th Century the Catholic Church held onto and defended the Geocentric Model as the divine order of planetary alignment and man’s hierarchy in
