Kristen Magliola 9/9/13 BIO: 414L Lab Report: SOC Medium I. Purpose: To make liquid and solid media for microbial growth II. Background: There are four different types of media used to grow microbes. They consist of Enriched media‚ Nutrient media‚ Selective media‚ and differential media. Enriched media is a growth media supplemented with complex biological molecules. This type of media is used for blood‚ coagulated blood‚ amino acids‚ etc. Nutrient media provides nutrients necessary

Air is an example of a gaseous solution. When dry is made up of oxygen gas dissolved in nitrogen gas. b. Liquid Solution- contain a liquid solvent in which gas‚ liquid‚ or solid is dissolved. Water is the most common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in

Mixtures INTRODUCTION A mixture can simply be defined as a substance that is made up or consists of two or more elements and/or compounds that are physically combined but that have not reacted chemically to form new substances. A mixture may be a solid‚ liquid‚ gas‚ or some combination of those states. Mixtures can be found almost every wher in our everyday lifes and some common examples are * sand and water * salt and water * sugar and salt * Due to the fact that mixture are not

determine the densities of some solids and liquids. To apply the rules of significant figures when reporting the weight‚ volume‚ and density of each material. To apply our knowledge about the Water Displacement method to determine the Volume of an irregular solid. The procedure in getting the Volume of a regular solid is different from an irregular solid. We use the Water Displacement method to get the Volume of an irregular solid whereas in a regular solid‚ we only multiply the length‚ width

Even though they are vibrating this is not enough to disrupt the structure. When a solid is heated the particles gain energy and start to vibrate faster and faster. Initially the structure is gradually weakened which has the effect of expanding the solid. Further heating provides more energy until the particles start to break free of

pressure transmitted out to the surface or envelope of the liquid‚ but within the fluid itself the particlesare all pressed together. When a solid is immersed in the liquid it is pressed at every point of its surface in the direction perpendicular to the surface at that point.(3) In every horizontal layer throughout the liquid the pressure per unit area is the same; and this is the case independently of the shape of any vessel in which the liquid may be contained. The pressure per unit area in any horizontal

there are three main sections‚ Solid‚ Liquid‚ and Gas. The main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone she can. A solid is hard‚ strong‚ and stable in
