A meal contains 30 grams of carbohydrate, 10 grams of fat, and 5 grams of protein. How many calories did the meal provide

230 Calories

Explanation:

Carbohydrates are the primary source of energy in our body and 4 Calories of energy is provided by each gram of carbohydrates. So 30 gram of carbohydrates will produce;

                              30 x 4= 120 Calories

Proteins also provide 4 Calories/gram.

                               5 x 4 = 20 Calories

Fats provide more energy than carbohydrates and proteins and 9 Calories of energy is provided by each gram of fat.

                               10 x 9 = 90 Calories

Totall energy produced by 30 grams of carbohydrates, 5 gram of proteins and 9 gram of carboydrates;

                         120 + 20 + 90 = 230 Calories

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.
