What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x?

The correct answer is 400 times.

Explanation:

The procedure of amplifying the ostensible size, not the physical size of something is known as magnification. This amplification is enumerated by a calculated number also known as magnification. Generally magnification is associated with scaling up of images or visuals in order to witness the details more clearly, with the use of printing techniques, microscopes, or digital processing.  

In the given case, in order to find the magnification, there is a need to multiply the objective power and the power of the ocular lens, that is, M = O × OL

It is mentioned, that Objective power = 40 times and Ocular lens power = 10 times,  

Therefore, M = 40 × 10 = 400. Hence, the magnification of the sample is 400 times.  

and after water is usually warmed by the sun the water temperature raises and then evaporates .

i believe it is c: genes for body color and wing size are inherited separately from each parent.
