please mark answer as brainliest and follow me

Explanation:

Dry raisins undergo a process called osmosis. ... Dry raisins swell up because they undergo Endosmosis. When the raisin is placed in a hypertonic solution i.e. water then thewater penetrates through the semipermeable membrane i.e. the skin of the raisin and hence the raisin swells up.

Answer 2

Explanation:

when we put rasin in the water, after sometime it gets swell because of the process of osmosis as concentration of the water is higher then the dry resin, so when we put it in the water it started to move from higher concentration to lower concentration that's why resin placed in water swells .
