The locations of molecules A and B at the beginning of the experiment are shown. Which statement best describes what was observed when the set up was examined 20 minutes later? A. Molecule A remained inside the artificial cell and molecule B remained outside.
B. Only molecule A was found both inside and outside the artificial cell.
C. Only molecule B was found both inside and outside of the artificial cell.
D. 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.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
