Annalisa is studying the fossilized remains of the extinct organisms shown. She notices that each of these species has a segmented body, similar to modern arthropods, such as lobsters and spiders. Which statement is the most likely explanation for this observation? A- The organisms evolved to mimic modern arthropods.

B-The organisms share a common ancestor with modern arthropods.

C- The organisms lived at a time when modern arthropods also lived

D-The organisms were all found geographically close to each other.​

The organisms evolved to mimic mordern arthropods

this is a good question! i'll do some research and come back when i have the answer!

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.
