A block with a volume of 12 cm3 has a density of 3 g/cm3. The block is cut into two pieces. One piece has a volume of 8 cm3, and the other piece has a volume of 4 cm3. What are the densities of the two pieces? A. The larger piece has a density of 2 g/cm3 and the smaller piece has a density of 1 g/cm3. B. The smaller piece has a density of 2 g/cm3 and the larger piece has a density of 1 g/cm3. C. The two blocks both have densities of 1.5 g/cm3. D. The two blocks both have densities of 3 g/cm3.

hello my name is kailey,

i think the answer is false i   hope this

carbon

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.
