My little brother’s science teacher gave him a mini project. The guiding question is “What brand of paper towels is best?” Basically, there are barely any rules whatsoever. You can do anything you want to justify your claim. So far, he thinks that he could measure absorbency or something. However, this isn’t set in stone What experiments can he conduct? What should his research question that is answered by the experiments be? What can he measure? For some context, the person who does the best work out of the grade gets a free A+ on an upcoming test. In conclusion, what can he do to conduct a successful experiment, sound smart, and possibly get that free A+?

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.
