In lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.

Answer:
D. Hydropower can harm native aquatic populations.
Explanation:
- Hydropower is the power of water or hydrosphere and is the cheapest and simplest form of energy. 
- The hydrosphere is a renewable source of energy and is thus non-polluting but most of the hydropower that is converted into electricity is harmful to the marine and aquatic life forms.

In early summer wasps, like bees, pollinate plants and flowers as they feed on nectar. If we were to eradicate all wasps, it would cause more problems than it would solve. So, wasps do serve a purpose, and despite being a problem at certain times of the year, they are a beneficial insect.
