Students are trying to decide which is better for the environment glass bottles or aluminum cans they intend to use a formal method of investigation to determine which container is better they are going to make a list of pros and cons for using each type of container but first need to do some research the students need to find out things like how much matter and energy are used to make the bottles and cans what are two other things the students should look at before evaluate him which container is better for the environment

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.

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.
