un atleta que pesa 70 kg y tiene una estatura de 1.70m requiere de una dieta balanceada de aproximadamente 12, 500 kj/dia. para mantenerse en forma competitiva su diete debe contener 60% de carbohidratos, 28% de proteinas y 12% de lipidos. con base en eestos datos y en los valores de contenido energetico calcula la cantidad en gramos por dia que debe consumir de cada uno de los nutrientes

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.

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
