![]() Electrical circuits consist of the following components: an energy source to provide voltage, conductors to allow current travel, insulators to limit current travel, and a load. Although most solutions we encounter are liquid, solutions can also be solid. Understanding the relationship between current, voltage, and resistance allows engineers to design efficient, safe, and functional electrical circuits. Biomedical science professionals approach complex problems systematically and logically by. The specific compositions of both of these solutions are not fixed, however, but depend on both source and location for example, the composition of tap water in Boise, Idaho, is not the same as the composition of tap water in Buffalo, New York. KS 1.2.3 Draw logical conclusions from experimental data. ![]() Thus air is a solution of nitrogen, oxygen, water vapor, carbon dioxide, and several other gases tap water is a solution of small amounts of several substances in water. Homogeneous mixtures are also called solutions. Examples of homogeneous mixtures are the air we breathe and the tap water we drink. Bacteria Bacteria E. If all portions of a material are in the same state, have no visible boundaries, and are uniform throughout, then the material is homogeneous. 1.2.3 Attack of the Superbug Jose De Leon SUMMARY SUMMARY We tested two strains of bacteria each have a diffrent resistant genes and is located in different areas to see if they will share their gene in order to survive the Antibiotics. Air, tap water, milk, blue cheese, bread, and dirt are all mixtures. Very few samples of matter consist of pure substances instead, most are mixtures, which are combinations of two or more pure substances in variable proportions in which the individual substances retain their identity. Oxygen, for example, is a pure chemical substance that is a colorless, odorless gas at 25☌. Figure used with permission from WikipediaĪ pure chemical substance is any matter that has a fixed chemical composition and characteristic properties. Gases completely fill their containers, regardless of volume. ![]() ![]() Liquids have a fixed volume but flow to assume the shape of their containers. ![]()
