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.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
