What is an indicator
200
These are the very tiny units that are used to measure objects through the microscope
What are micrometers
200
This is the ability of a microscope to make an abject appear larger
What is magnification
200
These are used to magnify the specimen, there are usually 2 or 3
What are objective lenses
200
This typically fills the cell

200
This is used to identify a particular organism by working through a series of steps which eliminate other organisms
What is a dichotomous key
300
This is used to measure volume of a liquid

300
This is the microscope used for dissecting a specimen

300
This is used to separate mixtures of molecules using filter paper
What is chromatography
400
This is the quantity of matter in something, and is found by using a triple-beam balance or electronic balance
What is mass
400
This is used to avoid the drying out of a specimen when using a compound light microscope

500
This is the name of the curving surface created when a liquid is placed in a graduated cylinder
What is a meniscus
500
This is used to create contrast when observing cell parts through a microscope
What is staining
500
This is used to focus under high power, sharpen the image under low power, or used to see the different layers of a specimen
What is the fine adjustment
500
These are most easily seen in cells undergoing mitosis or meiosis
