What do you think is meant by the statement “the human digestive system is very efficient at squeezing everything it can out of any food? " how do you think this relates to the way biomolecules are broken down and used by the body?

I think the statement “the human digestive system is very efficient at squeezing everything it can out of any food?" refers to the way the stomach is good at absorbing the wanted nutrients and keeping them in the body, while disposing of the unwanted waste and toxins. The biomolecules are broken down to preserve only certain nutrients within the molecules.

The statement means that the human digestive system can adapt to extreme diets in order to survive. For example, carbohydrates can be broken down into sugars and used for energy. But when carbohydrates are not available in the required amount, it can also break down fats to provide the body with the required amount of energy. This explains why Deb has enough energy to keep going, even on her extremely limited diet.

explanation:

i was told this before by a teacher, so yeah

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.
