Module 01 Homework Assignment
Use the information presented in this module along with additional outside research to answer the questions: Describe how applied microbiology is used to improve aspects of life and the environment. Microbiology is the study of microbes, which affect almost every aspect of life on the earth. Describe how the table of elements is ordered and discuss four common elements in living organisms. The current periodic table lists 109 elements.  It is arranged according to the periodic law; elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern. Elements that have similar properties are arranged in groups or families in vertical columns, the horizontal rows are called periods. Hydrogen, Oxygen, Carbon, Nitrogen; Hydrogen and oxygen are in the water that makes up most of our bodies. Carbon is what they mean when they say "carbon based life forms" Nitrogen is also very common in organic molecules. Describe the pH scale and discuss the importance in living cells and tissues. The pH scale measures how acidic or basic a substance is; It ranges from 0 to 14. A pH of 7 is neutral, less than 7 is acidic, and a pH greater than 7 is basic. The PH scale is summarized by two main categories. Acids release Hydrogen ions while Bases release hydroxyl ions. The higher the hydrogen ion concentration the more acidic the solution. A Neutral PH is considered to be a 7, on a scale from 0 to 14. Acidic is on the low end of the scale while basic is on the high end of the scale. The PH scale is very important in living cells and tissues because everything inside the body has an “optimal PH”. This means that certain reactions cannot occur or are not as effective if the PH isn’t correct.
