Which statement below best describes the cause of the arrangement of smooth and spikey trilobite fossils observed in the fossil record above?
The smooth trilobites were able to dig deeper into the soil than the spikey trilobites because they did not have protruding spikes that
would catch on rocks in the ocean floor.
Smooth trilobites could no longer blend in with the soil and grew spikes as an adaptation to protect themselves from predators
gradually over time.
The smooth trilobites were not able to compete with the spikey trilobites for food and slowly became extinct as the spikey trilobites
O
became more dominant in the environment.
O
A change in the environment caused the smooth trilobites to no longer be well adapted for the conditions. Spikey trilobites were well
adapted to the new environment and begin to thrive.

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.

the correct answer is sex-linked recessive.
