Component One

The Data Quality Objectives (DQO Process) is a planning process that has been developed by the United States Environmental Protection Agency. This particular planning process is used when environmental information or data is used to make a choice between two specific alternatives or to make a derivation of contamination estimate. The process is also used in the development of acceptance and performance criteria that find use in the clarification of study objectives, defining of appropriate data type and the specification of potential errors of decisions that are then used as the basis for the establishment of the quantity and the quality of ...

Introduction

Osmosis is the process by which water molecules move from a region of low concentration of solute to a region of high concentration of solute through a semipermeable membrane (Van 3). Osmosis therefore can define the movement of water in and out of the cytoplasm of a cell. A solution with a higher concentration of solute molecules than that of the cell cytoplasm is said to be hypertonic to the cell. On the other hand, a solution with a lower concentration of solute than that of the cell cytoplasm is said to be hypotonic to the cell.
Purpose: The ...

Part 1

1.
1. Eye piece 5.Arm
2. Objective lens 6.Coarse adjustment knob
3. Stage 7.fine adjustment
4. Base
2. What is the procedure (step by step) which you followed to do gram staining? (20 points)
1. Obtain a tissue sample for the gram stain.
2. Two or three drops of the sample were placed on the glass slide.
3. Use the electric slide warmer, heat the smear. Alternatively, this can be done by quickly passing it over a flame. Although should be very quick to avoid distortion.
4. Add crystal violet to the ...

THE MICROSCOPE

The fundamental objectives of this report are to learn how to:
- handle and care about the microscope
- Identify various parts of the microscope such as the eye piece, arm, coarse adjustment knob, fine adjustment knob, base, nose piece, objective lenses, stage condenser, and Iris diagram.
- Define various terminologies used while using the microscope such as the total magnification, resolving power, working distance, parfocal and real and virtual images.
- And finally to observe stained slides of bacteria or the fungi.

RESULTS

Concerning how to care about the microscope, the following should be taken ...
