the two phases of Reconstruction? What policies or decisions helped to shape each phase? • One phase of the Reconstruction era was the presidential era which started after the assassination of Abraham Lincoln‚ the man to take his place was Andrew Johnson. But as stated in the textbook “Johnson was a bitter racist” (411) he was against the idea of black equality. In May 1865 a lenient policy toward the South was designed to try and re-establish the southern state governments. The second phase was the

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

Introduction To Scanning Electron Microscopy At the completion of the prac‚ the practical experience of operating a scanning electron microscope is sufficient to operate the particular machine in the future. During the experiment‚ two different gold plated samples are analysed under the SEM and compositional and topographic information is identified and analysed. Both the information is derived by changing the working distance‚ accelerating voltage‚ aperture size‚ probe current‚ resolution and

Kevina Smith Lab 1: Microscopy and the Metric System Part A: Microscopy Purpose The purpose of this experiment was to learn how to use a microscope correctly and perform wet mount slides accurately‚ thus becoming more familiar with the microscope. Hypothesis It would be hard to use the microscope without any kind of previous training and the parts of the microscope and their functions must be learned in order to use it properly. Materials & Methods Materials: 1. Filter

1) The condenser lens concentrates light and makes illumination of image more uniform. 2) The bending of light is also known as refraction. 3) Total magnification = ocular lens magnification x objective lens magnification. 4) The total magnification of an image is 1200x and the magnification of the ocular lens is 10x. What is the magnification of the objective lens? Y = objective lens 1200x = 10x X y 1200x / 10x = y y = 120x Objective lens magnification = 120x 5) The limit of resolution

Compare and contrast laser scanning confocal and multiphoton microscopy in 250-500 words. Both confocal and two-photon (multi-photon) laser imaging can generate 3D images by capturing a stack of optical sections at different focal planes. In confocal microscopy‚ a detector pinhole which rejects fluorescence from off-focus locations is used; while‚ two- photon microscopy is capable of giving 3D contrast and resolution (comparable to confocal microscopy) without the necessity for

can see the Moon’s phases even though the Moon doesn’t change. The Moon phases are the different stages of the Moon as it orbits Earth. This cycle is known as the Phases of the Moon. As the Moon circles Earth‚ the amount of light we see changes. These changes in light that we see are known as phases. As the Moon orbits around the Earth‚ the changing of light is known as waxing and waning. The phases have to do with the relativity of the Sun‚ Earth‚ and Moon. The phases help us determine what
