Temperatures in the winter drop because that part of the earth is tilted towardaway from the sun.

Away

Explanation:

During winter, the earth is tilted away from the sun. Due to tilting of earth away from the sun, the sun rays interact with the earth at shallow angle which causes the rays to spread more in the outward direction and thus the amount of heat energy that should reach planet earth at any given spot reduce.  

Also, the earth’s hemisphere which is tilted away from the sun have short days and long nights which prevents earth from heating and thus winter season occur.  

mammal

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.
