Write a "D" for Darwinism or an "L" for Lamarckism beside each statement. An environmental "stress" (predator or competition for food or habitat) will ultimately
"choose" which trait gets passed onto future generations.
An individual in a species "chooses" which trait gets passed onto future generations by
using traits more or less in their lifetime.
A zebra may be born slow but become fast during its lifetime because it is often
chased by predators. Its offspring will therefore be faster.
A faster zebra will not get eaten and therefore be able to reproduce and pass along its
genes for speed
Inheritance of acquired characteristics determine how a species changes over time.
Natural selection determines how a species changes over time.

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.
