In this week's lab exercise you will examine levels of air pollution in the Phoenix Metropolitan area. The measurable levels of different pollutants indicate an overall air quality index (AQI). Anthropogenic sources of pollution (Carbon monoxide, Ozone) are a major contributor to higher AQI values but particulate matter (PM-10) is also important in determining an AQI score. Choose all listed sources that would contribute to increased particulate matter (PM-10) levels. and EXPLAIN WHY YOU CHOOSE IT. DEFEND YOUR ANSWER choices: a. Water vapor from Tempe town Lake and local water parks b.Bovine flatulence from Shamrock Farms c.Dust from empty construction lots or a recent HABOOB! d.

- (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…arrow_forwardIn the alveoli Multiple Choice a)no exchange with the blood occurs. b) oxygen diffuses out of the blood while carbon dioxide diffuses into the blood. c) oxygen diffuses into the blood while carbon dioxide diffuses out of the blood. d) both oxygen and carbon dioxide diffuse into the blood. e) both oxygen and carbon dioxide diffuse out of the blood.arrow_forwardOxygen travels in the blood in order to reach cells in need of oxygenation.
