Definition of the parts of the microscope 1. Stage The horizontal surface upon which the slide is placed is called the stage. The slide is held in place by spring loaded clips and moved around the stage by turning the geared knobs on the stage. Th stage has two perpendicular scales that can be used to record the position of an object on a slide. This is useful if you want to quickly relocate an object. 2. Coarse adjustment The coarse adjustment knob located on the arm of the microscope

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

For this experiment‚ there were four onion bulbs labeled A‚ B‚ C‚ and D. Bulbs B‚ C‚ and D were each immersed in a different concentration of coffee. Bulb A acted as the control because it was not immersed in any concentration of coffee; instead‚ the onion roots grew in water. The following is a list‚ in order‚ of the concentration of caffeine bulbs B‚ C‚ and D were in: 0.1%‚ 0.3%‚ and 0.5%. Four test tubes were gathered to set up the experiment‚ each holding an onion bulb. After each day‚ every

In time immemorial living things (the biotic factors) and non-living things have been interacting with one another for one reason‚ which is to survive. Both factors interact in one grandiose community where-in all forms of ecosystems‚ such as: desert‚ savanna‚ tundra‚ tropical rain-forest‚ and the like; are deem to be found and this community is our planet earth. As found in many textbooks and other science oriented reading materials‚ the earth is also considered as an ecosystem as well because

Step Down DC to DC Converter Ivana Krezzel T. Almazan and Ruphina G. Gomez Introduction In our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications

This is why behavior and thought patterns are not easy to change. The unconscious component can be very deep and very old. We need to understand this‚ and then we can change the bad habits. According to Wilson‚ the first rule is do not rationalize‚ defend‚ justify or excuse your bad habits- no matter what. Second is put out and express

a psychiatric illness develops his or her own definition of recovery. However‚ certain concepts or factors are common to recovery. Some of these are listed below. More recently‚ SAMHSA released a consensus statement outlining 10 fundamental components of recovery‚ which can be viewed here. Hope Hope is a desire accompanied by confident expectation. Having a sense of hope is the foundation for ongoing recovery from mental illness. Even the smallest belief that we can get better‚ as others
