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 ...

Identification of mystery microbe based on its morphology and biochemical properties

The experiment was conducted to detect the species of a given mystery microbe. The microbe was subjected to a battery of tests in order to identify its physical and biochemical characteristics. Based on the tests, different possible microbe species were eliminated to finally arrive at the right conclusion. The possible microbes included Escherichia coli, Providencia alcalifaciens, Enterobacter aerogenes, Staphylococcus epidermidis, Klebsiella pneumonia, Micrococcus luteus, Serratia marcescens, Mycobacterium smegmatis, Sarcina aurantiaca, Pseudomonas aeruginosa and Bacillus licheniformis.
The first test conducted was to detect the Gram staining properties of the given microbe. This helped in identifying whether the given microbe had a thin ...

1. Introduction
Fluorescent protein development research has gained increased knowledge about the range in the color palette available from the Aequorea Victoria jellyfish. The wavelength emissions in the blue to yellow range are now better understood. [1] Another area that has seen a great improvement in knowledge is the understanding of emissions of the monomeric fluorescent protein emissions in the orange to far-red spectral region. [1] The spectral region of fluorescent in the orange to far-red is derived appropriate reef coral species. [1] This area of research ...

1. Inverted as magnification is negative.
2. Real Image as it can be projected on a screen.
3. Two reasons.
. A ray passing through the centre of either a converging or diverging lens does not change in direction.
.A ray that enters a diverging lens by heading forward the focal point on the opposite side exists parallel to the axis of the plane itself.
4. Magnification is negative as the image size is less than the object size itself.
5. They are all equal and there are no variations in the result.

Answers on Experiment: 13( As per as data given)

1. Image is upright ...

A lens is an optical device used to alter the path of light in various optical applications. Lenses alter the path of light through refraction, which is phenomenon whereby the path of a ray of right shifts when it through materials with different density levels. Lenses are made from transparent materials, such as plastic or glass, which have been molded to give the required shape. A lens can be termed as either simple lens made from a single material, or a compound lens, which consists of an assembly of multiple lenses aligned along a common axis. Lenses are used ...

Abstract

Water is an important chemical owing to its various uses by living things. Most chemical reactions within the bodied of living things require water in order to occur. It is purported that life evolved from water some 3.8 billion year ago following the organization of inorganic and organic molecule to form as prokaryotic cells. Besides, the well being of a cell is overly dependent of the balance between the water and the dissolved substances in the water. In this regards, the cell can permit water molecules to move in and out of the cell; the process in called Osmosis.
