Introduction to ScienceEXERCISE 1: DATA INTERPRETATIONDissolved oxygen is oxygen that is trapped in a fluid. Since many living organisms requireoxygen to survive, it is a necessary component of water systems (streams, lakes, rivers, etc.).Dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4,which shows the amount of dissolved oxygen present in a body of water and the number of fishobserved in the sample. Then, answer the questions below.Table 4: Water Quality vs. Fish PopulationDissolved Oxygen (ppm) 0 2 4 6 8 10 12 14 16 18Number of Fish Observed 0 1 310213 15 10 12 131. What patterns do you observe based on the information in Table 4?The more dissolved oxygen in the water thehigher the & fish population2.

WATER QUALITY LAB – Quality of Natural Waters – Physical and Chemical Factors Read the background information and answer the Pre-Lab question. BACKGROUND We depend on a clean water supply for drinking, cleaning and sanitation, recreation, manufacturing, and for many other purposes. Public health officials and environmental biologis have developed tests that help monitor the quality of natural waters and locate sources, and potential sources, of water pollution. In this laboratory activity, you will test water samples collected from local waterways and assess them on the basis of several of the characteristics that scientists use to rate the quality of a body of natural water. Temperature One of the most significant characteristics of a body of water is its temperature. Among other things, temperature affects the solubility of oxygen in water, the rate of photosynthesis of aquatic plants, the metabolic rate of aquatic organisms, and the susceptibility of aquatic species to toxins and…

Mono lake is a a soda lake (highly alkaline- pH 10) formed some 700,000 years ago. In your research, you have discovered a novel organism that is about 5x2 um in size. It is an aquatic organism, that appears to thrive in low oxygen tensions and in alkaline conditions, and appear to be chemotactic . It was found in the deeper regions of the lake with higher salinity and no oxygen. You are attempting to classify the organism as a Bacteria, Archaea or Eukarya. For each of these domains, list five (5)characteristics or structures that would allow you to classify the organism as belonging the domains. This is, for each domain, list 5 distinct characteristics or distinct structures that would place the organism in that domain. Be thoughtful, specific and detailed in your answer (by detail, I am referring to the level of detail in the text -- for example, if you believe your organism has flagella, what flagella composition/structure/movement would classify it as Archaea vs Eukarya vs…
