Each thread layer comes into focus separately because the specimen is three-dimensional (it has thickness). By moving the fine adjustment knob back and forth, the layers of the specimen will come in and out of focus.

You have asked "how many cell layers are there in an Elodea cell". Obviously a cell cannot contain layers of cells so your original question is nonsense. What you should have asked is "how many cell layers are there in an Elodea leaf?". Read it again. Think about it. Think until it hurts then think some more. It's not my fault you can't see them. If you have as much trouble seeing what's there as you seem to have reading what you've written I'm not surprised. The way to see two layers of cells is to focus on one layer and then change the focus so that the other layer comes into view. To show there are two layers by continually altering the focus in ONE direction only you should be able to move through the sequence:- no layer in focus > one layer in focus > other layer in focus > no layer in focus

focus knobs are the things you use to focus stuff on a microscope.
The focus of an earthquake is the location within the lithosphere where seismic energy is released when slippage first occurs along a fault line. The epicenter is the location on Earth's surface directly above the focus.
Either Fine or Coarse adjustment.
To determine which fiber is on top in a thread slide, look for the one that is most prominent or appears closest to the viewer's perspective. Factors such as thickness, color, and texture can also help identify the topmost fiber. Orienting the slide under a microscope or using a hand lens can provide a clearer view for accurate identification.
M12 x 1.5 ( Metric ) thread
In a 2003 Ford Focus : The engine coolant reservoir is on the passenger side of the engine compartment ( it has a thread on pressure cap )
On a 2001 Ford Focus : The thread on cap on your engine coolant reservoir is the pressure cap / radiator cap
All the threads can be in focus again using the high-power objective if a certain thread is focused using the control knob to make adjustments. The knob allows for very small changes to be made which will create a precise focus.
The Layers Magazine specializes in Adobe products such as Photoshop, Flash, and Acrobat. They write reviews, articles and tutorials on how to better understand their products.
Don't ask, it's metric and I'm an American.

It tried to overturn Jim Crow laws.
the first place where the movement first occurs in an earthquake is the focus.
look at the focus fanatics forum... this thread should help http://forums.focaljet.com/spi-tuning/503448-egr-tube-sheared-header.html
