Which neuroanatomical method provides an outline of entire neurons, allowing us to measure cell body size and density? a. immunocytochemistry b. nissl stain c. golgi stain d. horseradish peroxidase?

Answer;

B. Nissl stain

Explanation;

-In Nissl staining, cresyl Violet Acetate solution is used to stain Nissl substance in the cytoplasm of neurons in paraformaldehyde or formalin-fixed tissue.

- The neuropil will be stained a granular purple-blue. This stain is commonly used to identify the neuronal structure in brain and spinal cord tissue.

-The Nissl staining method uses basic aniline dye to stain RNA blue, and is used to highlight important structural features of neurons. The Nissl substance  appears dark blue due to the staining of ribosomal RNA, giving the cytoplasm a mottled appearance.

explanation:

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
