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.

Economics as a course is divided into two major sub specialties, which are micro and macro economics. Micro economics has to do with the study of individual, households and businesses behaviors in decision making and uses of scarce resources. Macro economics on the other hand has to do with the study of how the whole economy behaves. Thus, macro economics is the study of how a nation's economy work and this usually involves the national government.
