Hydrolysis is when a polymer (such as a peptide bond or fatty acid) is split into smaller segments by adding water.
The answer is B because:
Cell walls are made of cellulose and proteins (hence II).
Animal cells don't have cell walls (only cell membrane) but plant cells do so IV
They must be semipermeable since materials for example carbon dioxide and water for photosynthesis have to go into the cell <em>some</em> way.
The theory is the Continental drift, the super-continent is called the Pangaea.
The answer to this question is exocytosis! This process allows particles to go through a small hole in the cell wall to enter other parts of your body! I hope this helped
