Answer:
The relation between individual and society is very close. Essentially, “society” is the regularities, customs and ground rules of antihuman behavior. These practices are tremendously important to know how humans act and interact with each other. Society does not exist independently without individual.
There are 6 type of simple machines, one of which is lever. Hammer is an example of lever. Levers are rigid bars that are pivoted at one point called a fulcrum, that is your hand. This is also the point where you apply force that is being maximized along its length to make it easier to pin down the nail.
Answer:
When selecting the proper microscope to view a sample, you should choose a simple microscope to look at a fresh lung tissue (whole organ), a compound microscope to observe the patterns of cells on a slide, and an electron microscope to study individual organelles within cells in great detail.
Explanation:
Many types of microscopes are available, they are used by researchers, medical technicians and students on a daily basis upon their need.There are different kinds of microscopes.
The simple microscope is generally considered to be the first microscope ,it provides information about biological specimens. Its magnifying power ranges between 200 and 300 times. it can easily be used to magnify a whole tissue.
With two lenses, the compound microscope offers better magnification than a simple microscope,the second lens magnifies the image of the first is high magnification, which allows users to take a close look at objects too small to be seen with the naked eye, observing pattern of cells.
Electron microscopes uses electrons rather than light for image formation, creating a magnified image, and samples are scanned in a vacuum so they must be specially prepared. An electron microscope offers a high degree of both magnification and resolution, making it useful to study cells in detail.
