oxygen increases so does the number of fish observed. However‚ when the dissolved oxygen reaches 14 ppm the number of fish decreases to 10. So‚ 6ppm and 14ppm‚ 8ppm and 16ppm‚ and finally 10ppm and 18ppm‚ have a similar number of fish observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If the amount of dissolved oxygen is increased‚ then the number of fish observed will increase. 3

TITLE: Wad a Watershed Lab INTRODUCTION: Using models is very important in science. In this lab‚ you will design a model that will help you investigate the relationship between land surfaces and water on Earth. OBJECTIVE: To design a model that will help you visualize watershed characteristics. PROBLEM: How can we use the relationships between land surfaces and water to understand conservation of resources and pollution? HYPOTHESIS: In your own words‚ write a hypothesis about how the relationships

prey is reduced when the prey are at low densities c. the per capita feeding rate of predators is reduced when their density is high d. the per capita feeding rate of predators is reduced when their density is low e. none of the above Question 2. A copepod species (the predator‚ measured in copepods/m3 of water) feeds on algae (measured in cells/m3 of water) in freshwater lakes. Assume that the interaction is well-represented by the Lotka-Volterra predator prey model: where r = 1/week

purpose of this lab was to study the specific characteristics of cations and anions‚ and ultimately to be able to identify an unknown substance based on our studies and tests using the logic trees developed through the experiment. A logic tree is a graphical display of the findings from this lab which‚ through a series of yes/no questions‚ elimination tests‚ will help us to identify and unknown sample. This lab will result in 2 logic trees‚ one for identifying cations and the other
