Take a few minutes to look at pictures of humans and humpback whales. You can look for the images on the Internet or look through books in a library. After carefully studying them, try to answer these questions: What are the characteristics of each species?
Are some of these features similar to those of other species? Which species?
Based on similar physical features, do you think other existing species share an evolutionary lineage with either humans or humpback whales? Which ones do?

Here's what I put for my answer. I hope this help's a tiny bit!

Explanation:

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.
