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

that it is very hard work and a challenge. It is a challenge because of the patience and dedication it takes to learn how to produce a quality weld. This is a type of work that very few people go into college for‚ and even less try to make it into a career. I am aware that this job is in high demand in some parts of the country‚

another. This is called “genetic engineering.” Genetic engineering also refers to the artificial modification of the genetic code of any living organism. Genetic engineering changes the original physical nature of the organism‚ sometimes in ways that would never occur in nature. Genes from one organism are inserted in another organism‚ most often across natural species boundaries. Some of the effects become known‚ but most do not. There are some examples of genetic engineering that have created chicken

place‚ scientists‚ specifically biologists‚ are becoming keener to the field of engineering. Genetic engineering that is. When one thinks of “genetic engineering‚” the first thought is probably a perfect child‚ or paradoxically some inconceivable creature‚ forged under the microscope in a scientific laboratory. Though both of these are genetic engineering‚ many people do not consider other things‚ such as genetic engineering of agriculture and medicine‚ both of which are extremely useful. Through the

Genetic Engineering Although genetic engineering is an entirely new field‚ it has fascinated mankind for many years. Genetic engineering gives the power to change many aspects of nature and could result in a lot of life-saving and preventative treatments. Today‚ scientists have a greater understanding of genetics and its role in living organisms. However‚ if this power is misused‚ the damage could be very great. Therefore‚ although genetic engineering is a field that should be explored‚ it needs

An electric battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell contains a positive terminal‚ or cathode‚ and a negative terminal‚ or anode. Electrolytes allow ions to move between the electrodes and terminals‚ which allows current to flow out of the battery to perform
