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
The student should adjust the focus back to the original position and then switch to the second layer of cells. It is important to refocus when changing layers to ensure a clear view. Adjusting the focus will help bring the second layer into clear view under high power.
When focusing the object under low power, you should use the coarse focus knob first to bring the object into general focus. Once the object is roughly in focus, then you can use the fine focus knob to sharpen the image.
When practicing the breathing technique of alternating between breathing in and out of one nostril, you should focus on the right nostril first.
The lens in your eye is located behind the iris, in the front part of the eye just behind the cornea. It helps focus light onto the retina at the back of the eye, allowing you to see clearly at different distances.
No, when using the scanning power objective lens on a microscope, only one colored thread will be in focus at a time due to the limited depth of field at this magnification. The other threads will appear blurry.
On high power and by focusing the fine adjustment, you will be able to see the fibers one at a time. As you focus, different threads will come into focus at different times. The one that comes into focus the first should be the top thread, the one that comes the second should be the one under that, and so on and so forth.AnswerOn high power and by focusing the fine adjustment, you will be able to see the fibers one at a time.

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
Earth's compositional layers refer to the different materials that make up the planet (crust, mantle, core), while its structural layers refer to the physical attributes and properties of these layers (lithosphere, asthenosphere, mesosphere, outer core, inner core). The compositional layers focus on the elements and compounds present, while the structural layers focus on how these layers behave and interact.
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.
Don't ask, it's metric and I'm an American.
The chemical layers of Earth refer to the composition of its layers, primarily categorized into the crust, mantle, outer core, and inner core, each defined by distinct materials and chemical properties. In contrast, the physical layers of Earth emphasize the mechanical behavior and physical state of these layers, which include the lithosphere, asthenosphere, mesosphere, outer core, and inner core, characterized by differences in temperature, pressure, and solidity. Essentially, the chemical layers focus on "what" the layers are made of, while the physical layers focus on "how" they behave under various conditions.
