Module 01 Homework Assignment

Use the information presented in this module along with additional outside research to answer the questions:

1. Describe how applied microbiology is used to improve aspects of life and the environment.

Microbiology is the study of microorganisms (VanMeter, VanMeter, & Hubert, n.d., p.3). These are all of the things not visible to the human eye. With the study of microbiology, it enables us to find things such as viruses and bacteria. This is helpful because sickness and certain outbreaks can be prevented. In turn, this creates a safer more stable environment.

2. Describe how the table of elements is ordered and discuss four common elements in living organisms.

Elements are ordered on the Table by their atomic number. This is also the number of protons in the atomic nucleus. The four most common elements in living oprganisms are Hydrogen, Carbon, Nitrogen, and Oxygen. (VanMeter, VanMeter, & Hubert, n.d., p.20).

3. Describe the pH scale and discuss the importance in living cells and tissues.

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. (VanMeter, VanMeter, & Hubert, n.d., p.27-28).

4. List five specific areas for which clinical laboratories are responsible.

Microbiology, Hematology, Urinalysis, Biochemistry, and Immunology. (VanMeter, VanMeter, & Hubert, n.d., p.100).

5. As new chemicals come into a laboratory, what is a good source of information regarding the handling and storage of the substance?
