Answer:
Different types of microscopes use different sources for magnification, have different levels of magnification, and can help in visualizing an object in two dimensions or three dimensions.
Thus, if the same object is observed under different microscopes the differences we can observe is the resolution, magnification, and plane (2D or 3D) of the object.
For example, a compound microscope can magnify up to 500x whereas stereoscopic microscope can only magnify up to 50x.
The answer is c because the precession of the ecliptic was component of a milankovitch cycle and is related to periodic ice ages through out history
Answer:
Taking more samples from different parts of an acre.
Explanation:
Validity and accuracy of the data is crucial for any serious research. In this particular case, the most accurate data would be obtained if earthworms would be counted on the whole acre. Of course, this would consume lot of time, people, money etc. That's why methods for estimation are used. Estimation best works with large number of samples. Since one acre equals over 4000 square meters, taking only five samples from such a big area is simply not enough for obtaining valid data.
One of the possible ways to improve estimation is to take more samples per acre while avoiding taking adjacent samples because it could be possible that number of earthworms in one part of an acre is increased (or decreased) for any reason, which would lead us to wrong conclusion.
C, as A,B, and D aren't true.
