An unknown alien body visits earth. scientists study it to determine if it is alive and
notice the following things about it:
. it is made of cells
. it can reproduce
. it does not grow or develop
. it does not maintain homeostasis
it can adapt to its surroundings
. it uses energy
based on these observations, is this alien living or not?
it is living because it is made of cells, uses energy, and reproduces
it is living because it has all the characteristics of life
it is non-living because it does not have all the characteristics of life

The answer is A, it is living because it is made of cells, uses energy, and reproduces.

Explanation:

thinking it would be d not too sure but i think it's right

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.
