The locations of molecules a and b at the beginning of the experiment are shown. which statement best describes what was observed when the setup was examined 20 minutes later?
1. molecule a remained inside the artificial cell and molecule b remained outside. 2. only molecule a was found both inside and outside the artificial cell.
3. only molecule b was found both inside and outside the artificial cell.
4. both molecules a and b were found inside and outside the artificial cell.

3. Only molecule B was found both inside and outside the artificial cell.

Explanation:

-  Molecule A is smaller than molecule B.

-  Molecule B has an electrical charge.

-  They could be different sizes.

-  size of the molecule

-  One is a sugar or monosaccharide and the other is a starch or polysaccharide.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

. thus, if a hepatectomy (ablation) of 70% of the hepatic mass is performed in the rat, there is complete recovery in 7 to 10 days.
