(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1.Insufficient dissolved oxygen is necessary for the life of fish and other aquatic organisms. As aquatic photosynthesis is light dependent, the dissolved oxygen produced will peak during daylight hours and decline at night. 2. The potability or “drinkability” of tap water varies from place to place. The distillation process ensures that contaminants are left in the boiling vessel, which results in a cleaner and more pure water in the collection vessel. 3. The stable form of oxygen in the Winkler Titration Method in determining the dissolved oxygen in water was magnesium dioxide. The free iodine in the Winkler Titration Method turned the solution into a red color.

4. Tap water is more pure than distilled water. The purity and cleanliness of distilled water remains constant no matter where you get it from, because of the process it has undergone.
5. Carbon dating is an application of nuclear chemistry where they use the amount of C-14 in a fossil to determine its age. Nuclear power plants produce radioactive wastes.
