Lab 2: The Metric System and Microscope Name _________________________ Date __________________________ Section 1: The Metric System The Metric System is known as the International System of Measurement. The Metric System is based on Standard-prefixes that correspond to ‘multiples of 10’. The measurements of volume (the liter)‚ mass (the gram)‚ and length (the meter) are the baseline for all metric unit conversion factors. In the United States‚ the English System is more commonly used;

BIO Microscopy‚ Mitosis‚ and Motility Lab Discussion Questions In the Microscopy‚ Mitosis‚ and Motility lab‚ the class used the Compound Microscope. The Compound Microscope helped examine the prokaryotic and eukaryotic cells‚ observe the different stages of mitosis‚ and compare modes of motility used by protists. The light compound microscope works with the aid of lenses such as the eyepiece. These lenses help keep the focus of the light on the eye. The fine and course adjustments also assist with

Paper submission on electron microscopy professor: Ernesto Suarez by ananthalakshmi adapa University of Hartford What is a electron microscopy? An electron microscope (EM) is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image. An EM has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about

Cellular and Molecular Techniques - Lab #1 BIO 349 Lab Report #1 Microscopy and Staining Abstract The primary focus of this lab was on microscopy and simple stains. Microscopy that was used were magnification‚ slide preparation‚ and staining. Methylene blue‚ a simple staining component‚ was used to stain the slide in order to see the different microbes and determine their cellular shape. Introduction The purpose of this lab was to become familiar with the light microscope and how

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

the metric system. Many countries have completely switched over to using the metric system. America is not one of these countries. The question is: should America switch? The rest of the world uses it‚ so why not America? It seems to make more sense than the current system. However‚ there are costs in converting. Lots of money will be spent by companies trying to switch everything over. Also‚ is the metric system actually sensible to use? The answer is yes‚ and America should use the metric system

Should the United States adopt the SI units/metric system or keep the American standard system? This is a question that has been arising since the invention of the metric system in France‚ 1790. Thomas Jefferson‚ president at the time of the invention‚ was deciding whether to adopt the system at the time in which he included on the constitution. I think that the metric system should be adopted in America‚ not only to please others‚ but to benefit us. The SI units are easier to use‚ would be more

the metric system! Does the United States use the metric system? Nope! America is that stubborn 5 percent that refuses to conform‚ allowing needless mistakes to happen. The metric system was carefully fashioned with a logical‚ systematic pattern; whereas‚ the United States customary system is a hodge-podge system of measurement based off of the old English system. England gave up their antiquated system‚ which was developed without purpose over the coarse of 200 years‚ to conform to the metric system;

Why isn’t the metric system used more prominently in the United States? Since I was a child‚ I can remember the disagreements among school boards in the early 1970’s about transition my school to the metric system. It was a voluntary transition and many school did not want to implement it. When I was n elementary school the opposition came from the parents believe it or not. They said they would not be able to help their children with homework‚ etc. Actually looking back on it‚ parents did not
