You were looking at an organism that was microscopic, but too small to be magnified with a compound microscope. You
also need the image to be of the outside surface of the
organism. Of the microscopes below, which option is the
best fit for the criteria you need to meet?
Select one:
O a Scanning electron microscope
Ob. Dissection microscope
Oc Compound light microscope
Od Transmission electron microscope

Scanning electron microscope.

Explanation:

We can answer this question by process of elimination.

A dissection and compound light microscope have too small magnification for this question. Transmission electron microscopes allow the electrons to pass through the subject, visualizing the inside, while scanning electron microscopes capture the exterior (or as the problem worded it, the surface). Therefore, scanning electron is the right answer.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
