Dillard recalls as a child obbessing over watching the algae in her “child’s microscope set”. She was so

Why is special paper used to clean the lenses of a microscope? (1 point) Because fibers in towels and cloths may contain foreign material which could scratch the lens and marks or lint‚ could be left on the lens making it appear dirtier than before 4.

etched onto its surface‚ which is inserted into the eyepiece lens. • The size of the eyepiece graticule remains constant‚ despite the fact that the image viewed will change its size depending upon whether high- or low-power objective lenses are used. For example a cell viewed with the x40 objective will appear much larger than when viewed with the x10 objective. However because the graticule is in the eyepiece it will not change its size. Therefore the value of each of

Exercise No. 1 Micrometry: The Science of Standardized and Calibrated Micrometric Measurements (The Jellybeans) Joaquim B. Aganon‚ Glaiza S. Ibanez (14 August 2014) (21 August 2014) I. Introduction Microscopes and the field of Science are two inseparable things. Almost all Sciences are associated with the use of a microscope‚ a device use to view objects which are not visible to the naked eye. The term microscope came from the Greek term “Mikros” which means “small” and “Skopien” which means

Lab 4 Tissues Purpose: The purpose of this lab is to disover Histology or the study of tissues. Tissue make up a large part of our bodies and in this lab we will learn about the different types and functions of tissues. Hypothesis: I believe at the end of this lab If I am willing to do the reasearch the I will be able to use a mircoscope to look at different tissue samples and learn about the many types of tissue cells and their functions.
