Asample of food containing one type of a large molecule was treated with a specific digestive enzyme. nutrient tests performed on the resulting products showed the presence of simple sugars, only. based on these test results, the original large molecules contained in the sample were molecules of

protein
glucose
starch
dna

The best answer is starch.

Starch is a type of carbohydrate.

Carbohydrates are made of simple sugars, namely glucose. A simple sugar is a single molecule of a sugar. A single sugar  molecule is called a monomer.

Starch is made of many monomers or units of glucose linked together and is thus called a polysaccharide. When it is broken down, the result is its many glucose units are separated from each other by breaking the chemical bonds that hold them together, and are thus released as simple sugars.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.

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.
