Based on their locations on the periodic table, which best compares the properties of the metalloids arsenic (As) and antimony (Sb)? Arsenic has a more metallic behavior than antimony because arsenic’s atoms have fewer electron shells.
Arsenic has a more metallic behavior than antimony because arsenic’s atoms have more electron shells.
Arsenic has a more nonmetallic behavior than antimony because arsenic’s atoms have more electron shells.
Arsenic has a more nonmetallic behavior than antimony because arsenic’s atoms have fewer electron shells.

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.

the answer is cell division : )

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
