Athletes prepare for big competitions by consuming high amounts of pasta. what macromolecule are they filling up with, and why is this practice important for athletes?

The Athletes prepare for big competitions by consuming high amounts of pasta. They consume the pasta due to the macromolecules that is the carbohydrates and protein that are present in it.

Explanation:

Pasta is a wholesome food that contains a number of macromolecules such as protein and carbohydrates, the protein present is required to build the muscles whereas the carbohydrates is required for instant energy. In athletics the athlete needs strong built muscles and also it requires instant energy to fuel the activity.

yes it is   dangerous

explanation:

because that foot is discusting and could get you sick

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.
