Which microscope would be most useful for quickly estimating the number of red blood cells in a patient's blood sample?

Answer;

-Compound light microscope

Explanation;

-A microscope is an optical instrument for forming magnified images of small objects, consisting of an objective lens with a very short focal length and an eyepiece with a longer focal length, both lenses mounted in the same tube.

-Microscopes used in homes, schools, and professional laboratories are actually compound microscopes and use at least two lenses to produce a magnified image.

-A compound microscope is used for viewing samples at high magnification (40 - 1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample).

yes because some molds produce mycotoxins which can be very neurotoxic to the brain .
