Answer:

water molecules

hormones

Step-by-step explanation:

Water molecules can easily pass through semi-permeable membrane of the cell by Osmosis . Osmosis is a process in which molecules moves from a region of lower concentration to the region higher concentration through a semipermeable membrane of the cell. Water move easily as compared to other molecules because water has very small size.
