It is believed that old rocks are rare on ocean floors because the floor has many remains and we are not unable to reach them.

Answer from: Globug1144

At the mid-ocean ridges, lava is pushing the sea floor away from the ridge on each side. Eventually that part of the seafloor will be subducted under a continental plate at a convergent boundary. That means that the seafloor is constantly being renewed. The newest rocks will be found closest to the mid-ocean ridge and the oldest the greatest distance from the mid-ocean ridge.
The oldest rock found beneath the ocean dates back only about 200 million years.
However, the rock underlying the continents is as much as four billion years old.

Answer from: Quest

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.

Answer from: Quest

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
