Long, streamlined bodies reduce friction and allow access to small spaces. This body type is found among amphisbaenians, nematodes, and caecilians. Body shape in each of these organisms would be considered a(n):

homologous character

parsimonious character

phylogenetic character

analogous character

The analogous characters

Explanation:

In the given question, the body of the organism belonging to different phylum of animal kingdom shows the same structure and function although they are unrelated.

The streamlined body of the nematodes, the amphibians and the reptiles are similar in appearance and performs the same function. This trait has been the result of the natural selection as the same natural force has been applied to these three organisms which have resulted in acquiring the same type of adaptations in response to the same habitat.

The evolutionary biologists consider such organs as the analogous organs which are evolved through the convergent evolution.

Thus, the  analogous character is the correct answer.

the supermassive black hole is in the middle of the galaxy.

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.
