When a ink filler is dipped into a beaker of water and the bulb is pressed, air bubbles appear in the water . why. 1. Air in the atmosphere forms the bubbles
2. the air in the ink filler is released to form bubbles
3. the air in the water forms bubbles
4. the liquid rushes into the filler forming bubbles
5. None of these

the answer is "a.) well–developed vascular system."

explanation:

it is either c or d and i know for sure it is not a or b

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.
