You are given a slide of a pathogen that is gram-negative and whose subcellular structures can be observed with a light microscope. what most likely is this pathogen?

This pathogen is most likely to be a fungus.

Explanation:

Fungi are eukaryotic organisms typically having chitin cell walls, but no chlorophyll or plastids. Fungi may be unicellular or multicellular. Eukaryotic pathogens such as fungus are gram-negative when stained with Gram stain. Light microscope is usually used when viewing the results of Gram stain. A gram negative fungus will not retain the dye of the Gram’s stain and it will take on a pinkish color. Subcellular structures of fungi such as endoplasmic reticulum, Golgi apparatus and mitochondrion can also be observed when a fungus is viewed under a light microscope.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
