The diagram represents a cell in the field of view of a compound light microscope. In which direction should the slide be moved on the microscope stage to center the cell in the field of view? down towards C
A student views some cheek cells under low power. Before switching to high power, the student should
Center the image being
Focus with the coarse adjustment
A student changes the objective of a microscope from 10x to 50x. If this is the only change made, what will happen to the field of view?
The field of view will decrease.
The amount of light will decrease.
When an onion cell is stained with iodine, which organelle becomes more visible under the compound light microscope?
nucleus
To locate a specimen on a prepared slide with a compound microscope, Why must a student should begin with the lowpower objective rather than the highpower objective?
The field of vision is larger under low power than under high po.er
1. Which substance could be added to the slides to make the details more visible? a stain
2. What is the name of the stain used for animal cells? methylene blue
3. What is the name of the stain used for plant cells? iodine The diagram represents the field of view of a compound light microscope. Three unicellular organisms are located across the diameter of the field. What is the approximate length of each unicellular organism?
500um
Give the name and function of each structure labeled.
A – Eyepiece / Ocular: structure you look through
B – Fine adjustment: used to focus under high power
C – Arm – used to hold the microscope D –
BSC-2010C Lab 1: Microscope basics and the metric system. Purpose: To test my general knowledge of microscope use and its components and the use and conversions of the metric system. Hypothesis: The use of a microscope and its components are extremely hard to use and will take numerous years of use to master and the use and conversion of the metric system is extremely difficult. Materials & methods: Materials: General Use of the Compound Optical Microscope , Making a Wet Mount…
The First Image Ever of a Hydrogen Atom's Orbital Structure What you’re looking at is the first direct observation of an atom’s electron orbital — an atom's actual wave function! To capture the image, researchers utilized a new quantum microscope — an incredible new device that literally allows scientists to gaze into the quantum realm. An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had…
Week 9 Organisms Chemical Reactions CLICK link below to hear a Science Course Mentor provide an overview to this section, “Chemical Reactions”: http://wgu.connectpro.acrobat.com/p22134881/ Use Chapter 13 and Chapter 15, in Conceptual Integrated Science, to address the below items in your notes: 1. What happens during a chemical reaction? One or more new compounds are formed as a result of the rearagment of atoms. 2. Why is the law of conservation of energy important in chemical reactions?…
what we can see with light microscopes (the kind of microscope you'd find in a typical science class), versus what we can see with electron microscopes (very specialized microscopes found in large research facilities like universities). This should give you a better perspective on the comparative sizes of things. As you can see, cells are so small that we need a light microscope to see them. Molecules are so small that you can barely see them with the most powerful microscopes ever made, and atoms and…

You can get a copy of this sheet at the discussion board in the Cells Resource Site. Are you ready for the practical? As you finish studying for the practical, here is a review sheet for you to see if you are ready. Disclaimer: This is just an aide. It is not meant to be an exhaustive list (albeit it is pretty long) --- there may be questions on the practical about other items covered in lab that are not on this list. Each instructor asks questions in a different way so don’t memorize – LEARN.…

Using his instruments, Hooke was the first to describe cells. 6. Van Leeuwenhoek; the inventor of the simple (single lens) microscope. 7. Carl Zeiss and Ernst Abbe improved the compound light microscope, adding the condenser and improving the optics. 8. Schleiden and Schwann were the first to observe that all organisms were composed…
