1. On the compound microscope, how is total magnification calculated?
It is calculated by multiplying 10X the objective magnification power.
2. IN YOUR OWN WORDS, describe, step-by-step how to view a specimen with the compound microscope.
Step one prepare the specimen by getting a clean slide and put the specimen on it.
Step two put a small drop of microscope coloring.
Step three put a small plastic cover over the specimen.
Step four put the slide onto the microscope stage.
Step five starts with the lowest magnification and gradually increase the magnification power until the specimen is viewed clearly.
3. What difference in orientation did you note when you observed the letter “e” with the naked eye compared to when you observed the letter “e” under the microscope?
When the letter “e” was viewed with the naked eye, it appeared normal. In contrast …show more content…
PART A: CARBOHYDRATES
1. What chemical elements compose carbohydrates?
It composes of three elements which they are carbon, hydrogen and oxygen.
2. List AND define the three major GROUPS of carbohydrates.
1- Monosaccharides: consist of single sugar molecule it is also simple.
2- Disaccharides: consist of two sugar molecules joined together.
3- Polysaccharides: consist of eight or more simple sugars joined together.
3. Name at least one EXAMPLE of each major group of carbohydrate.
1-Monosaccharides: glucose and fructose.
2-Disaccharides: lactose and maltose.
3-Polysaccharides: starch and glycogen.
4. What are the functions of carbohydrates (list several functions)?
The functions of carbohydrates are providing energy, regulating blood sugar as well as saving proteins for other uses other than energy; also it helps in breaking down of triglycerides.
PART B: LIPIDS
1. What chemical elements compose lipids?
It composes of three elements which they are carbon, hydrogen and

Use one sketch to help you describe the steps that occur in order for the following events to occur in a skeletal muscle cell. a. Depolarization of the muscle cell membrane Voltage-gated channels opens and responses to changes in membrane potential. Rapid depolarization of the muscle cell membrane is caused by opening of…

\subsection{Test results} \label{sec:Test results} An optimized gas mixture of C$_2$H$_2$F$_4$/iso-C$_{4}$H$_{10}$/SF$_{6}$ = 95/4.5/0.5 was flown through the RPCs with a total flow rate of 10 SCCM and operated in the avalanche mode. The schematic of the gas flow system for two RPCs is shown in figure~\ref{fig:5_Gas_flow_system}. The following characterization studies were conducted on the RPCs at $\sim$45\% relative humidity (RH) and 20 $^{\circ}$C temperature. These are the optimized ambient…

Address each of these points in your own words (9 points). Why is it important to adjust the condenser when you are using a microscope? It is important to adjust the condenser when using a microscope in order to obtain a clear image of the specimen. The condenser focuses the microscope’s source of illumination and can be moved farther from or towards the stage in order to adjust the intensity of the light source. It is important that just the correct intensity of light be focused to have a clear…

2.7.1 Measurements XPS is used to measure: 1. Elemental composition of the surface (top 0 –10 nm usually) 2. Empirical formula of pure materials 3. Elements that contaminate a surface 4. Chemical or electronic state of each element in the surface 5. Uniformity of elemental composition across the top surface (or line profiling or mapping) 6. Uniformity of elemental composition as a function of ion beam etching (or depth profiling) Because the energy of an X-ray with particularwavelength is known…
