7 An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram,
such as the one shown below, is based on molecular data. It can be used to represent
evolutionary relationships within a group of organisms that are hypothesized to have
descended from common ancestor.

Spectacled bear
Giant panda

Which statement is best supported by the information in this dendrogram?
Ok

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.
