Background: Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed

per gram of substance‚ the greater the temperature change. The relationship between the heat added‚ the mass of a substance‚ and the temperature change it undergoes is known as specific heat. Specific heat is defined as the amount of energy necessary to produce a temperature change of 1°C per gram of substance. The specific heats of different substances vary‚ and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimetry. In this lab activity

Microbiology is the study of microorganisms which must be viewed with the aid of a microscope or electron microscope. The importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling

Introduction: The purpose of this lab is to use staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate
