They get a big block of it and put it to a grinder. Its atomic number is 58 and its chemical symbol is Ce. The last element I will discuss is neodymium. It is the best known out of the lanthanide series out of rare earths because of the one and only neodymium magnets. They are the strongest magnets in the world and there are many purposes

Chemical Senses OLFACTION The sense of smell. Begins with the detection of molecules suspended in the air Olfactory stimuli Must be soluble in fat Taken through the nostrils and circulated within the nasal cavities connected to the nostrils. Olfactory epithelium Thin sheet of cells which contain neural receptors for olfaction Contains olfactory receptor cells and glia-type support cells that produce mucus Also contains basal cells which give rise to new receptors when needed Olfactory

Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

4 The Chemical Basis of Life Introduction Your body is an elaborate chemical system. Chemical signals between brain less enable your mind to understand what you see. You nourish those cells with chemicals that are obtained from food. Life is all about chemicals and how they interact Concept 4.1 Life requires about 25 chemical elements Elements Humans and other organisms are examples of matter. Matter: Anything that occupies space and has mass. (Physical things)

Human Digestion SCI/241 Human Digestion The beginning of the digestive process starts with the smell and sight of food which activate the salivary glands. The mouth is the point at which food enters the digestive tract and continues the digestive process by chewing food. The food is then broken down into pieces and moistened by salivary glands which turn food into a bolus. The bolus goes down the pharynx into the esophagus which connects the pharynx to the stomach. The stomach is an organ
