Describe the generation of an action potential and draw and label the events that occurduring an action potential, compare and contrast the role of sodium and potassium voltage-gated channels in the generation of an axon potential, and explain what happens if either is blocked or stimulated (knowledge/comprehension/analysis/s ynthesis)

Comprehension is defined as the ability to grasp the meaning of material. ... These learning outcomes go one step beyond simple remembering of material, and represent the lowest level of understanding. Illustrative General Instructional Objectives Understands facts and principles.

Explanation:

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
