1. When a sugary gummy bear is placed in water, there are more dissolved solutes _______________ (inside/outside) the gummy bear
madreJ [45]

Answer:

When a sugary gummy bear is placed in water, there are more dissolved solutes inside the gummy bear.

Explanation:

The sugary gummy bear has more solutes as compared to the water in which it is being soaked. When a sugary gummy bear is placed in water, water enters the gummy bear through osmosis as water tends to move to the place where there are more solutes. The sugar gummy bear has more solutes. So, the gummy bear  expands and increases in size due to the entrance of water into it.
