Turn the revolving turret (2) so that the lowest power objective lens (eg. 4x) is clicked into position.
Place the microscope slide on the stage (6) and fasten it with the stage clips.
Look at the objective lens (3) and the stage from the side and turn the focus knob (4) so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip.
Look through the eyepiece (1) and move the focus knob until the image comes into focus.
Adjust the condenser (7) and light intensity for the greatest amount of light.
Move the microscope slide around until the sample is in the centre of the field of view (what you see).
Use the focus knob (4) to place the sample into focus and readjust the condenser (7) and light intensity for the clearest image (with low power objectives you might need to reduce the light intensity or shut the condenser).
When you have a clear image of your sample with the lowest power objective, you can change to the next objective lenses. You might need to readjust the sample into focus and/or readjust the condenser and light intensity. If you cannot focus on your specimen, repeat steps 3 through 5 with the higher power objective lens in place. Do not let the objective lens touch the slide!
When finished, lower the stage, click the low power lens into position and remove the slide.
Your microscope slide should be prepared with a coverslip over the sample to protect the objective lenses if they touch the slide.
Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.
Always keep your microscope covered when not in use.
Always carry a microscope with both hands. Grasp the arm with one hand and place the other hand under the base for support.
Answer:
B. Light
Explanation:
Light is electromagnetic wave. Electromagnetic wave is a type of wave which does not requires medium for its propagation so that's why light travel through space from sun and sound can't because sound is longitudinal wave which requires medium for its propagation. Electromagnetic wave is also called transverse waves. In transverse or electromagnetic wave, movement of oscillation is perpendicular to the direction of the wave.
Answer:
It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.
Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.
<span>Hypothermia is a condition that can cause a person to feel disorientated and result in the loss of motor control. Hypothermia is a grave condition that takes place when your body loses heat faster than it can produce it, resulting in a body temperature that is dangerously low.</span>
<span>linnaen classification was 2 kingdom classification,named plantae and animalia, on the basis of nutrition w.h.whittaker included 5 kingdom classification monera,protista,fungi,plantae,animalia.
so option b)plant and animal kingdom is right,
actually linnaeus put all protists,monerans,and plants in one kingdom plantae,though they have different cell structure,and mode of nutrition.</span>
