mols
Subject:
The mole is a unit of measurement for the amount of substance or chemical amount. It is one of the base units in the International System of Units, and has the unit symbol mol.[1]
The name mole is an 1897 translation[2][3] of the German unit Mol, coined by the chemist Wilhelm Ostwald in 1893,[4] although the related concept of equivalent mass had been in use at least a century earlier. The name is derived[5] from the German word Molekül (molecule).

Comparing global warming to ozone depletion
Subject:
The Difference Between Global Warming and Ozone Depletion Foreman Room 102 1. Global Warming and Ozone Depletion take place in two different layers of the atmosphere: Global Warming Ozone Depletion Global Warming vs. Ozone Depletion: Causes Global Warming: cars, factories, rice farming, landfills: Infrared heat enters but is trapped by the chemicals when it tries to escape. The chemicals act like a blanket. CO2 CH4 NOx CFCs H2O Global Warming vs. Ozone Depletion: Causes Ozone Depletion: Propellants (hairspray), Air Conditioners, some manufacturing. Chemicals react with UV protecting ozone in the stratosphere. CFCs CCl4 CF4 Ozone is good up high but bad nearby Global Warming vs. Ozone Depletion: Environmental Effects and Human Health: GLOBAL WARMING

Water is the most unique molecule in our lives. Water is a substance that gives the possibility of life on this Earth as we know it. All organisms that we are accustomed to are made up of mostly water and are habitually accustomed and dominated to water environments. Earth started out in water before land was even present. Our lives remain tied to water and all living creatures need water more any natural habitat that can be found as a solid, liquid or gas. The large quantity of water is the main reason we are able to reside on this beautiful home we call Earth.
harvesting energy from food
Subject:
Harvesting Energy from Food Cellular respiration involves catabolic pathways. Substances are being broken down. Pathways are exergonic. Couple an endergonic reaction with an exergonic reaction ADP + PI ? ATP 2 catabolic pathways covered that are exergonic and release energy to power endergonic reaction Cellular respiration begins with glucose. Aeorbic Fermentation begins with glucose. Anaerobic
