A small plastic bag is filled with a mixture of sugar and water. The bag is tied tightly and placed in a beaker of 100% water and locked in a cabinet. After two days, the water outside the bag is tested and the tests indicate there is sugar in the water outside the bag. What best explains this test result?
A.Sugar moved from an area of low concentration inside the bag to a higher concentration outside of the bag.
B.The plastic bag was selectively permeable and would not allow the sugar molecules to enter or leave.
C.The pores (holes) in the bag were large enough to let the sugar pass and passive transport occurred.
D.Sugar from the air moved into the water over time.
