Molecules that are eaten but not absorbed by the animal leave the animal's body in and are

I believe there are blanks in this question:

Molecules that are eaten but not absorbed by the animal leave the animal's body in __ and are __

For the first blank, the answer is “feces”.

While for the second blank, the answer is “not assimilated”.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
