Lab 1 – Introduction to Science Exercise 1: The Scientific Method Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organisms require oxygen to survive, it is a necessary component of water systems such as streams, lakes, and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from and then answer the questions below. QUESTIONS 1.

The Goldfish Experiment Abstract: The purpose of this experiment was to determine the effect of different water temperatures on the respiration rate of goldfish. According to the data obtained, the breathing rate of the goldfish increased as the water temperature increased, and diminished as the water temperature dropped. Using the data from all the groups, the average oral movements from the control goldfish ranged from 74 breaths per minute to 55 breaths per minute as time progressed, while the average oral movements of the experimental goldfish ranged from 141 breaths per minute to 49 breaths per minute as the temperature changed. Introduction: The objective of this experiment was to identify the effect of different water temperatures on the respiration rate of goldfish. Goldfish obtain oxygen from the water, and the process starts with water flowing into the mouth, over the filaments in the gills, which are located on the sides of the head, and out through the operculum, which is a flap located on each gill chamber.
Some of the effects caused by the pollution included: disruption of aquatic life, elevated levels of nitrates and phosphates from polluted underground water, swimming prevention, and numerous outbreaks of Avian Botulism. Since 2009, Predecessors of the Lake Huron
According to Frazer (2008), a majority of salmon aquaculture in the Pacific Northwest consists of non-native Atlantic salmon. This is an issue according to Simberloff (2009), because after changes to habitat, research indicates that, “… the second greatest cause of species endangerment and extinction [is introduced species] …” (p. 2). There are several factors associated with invasive species, not the least of which is the spread of disease. Bakke & Harris (1998, as cited in Frazer, 2008) mentioned that hundreds of infections that are rare in wild Atlantic salmon populations are prevalent in farm raised Atlantic salmon. Escaped farmed salmon are then capable of spreading these infections to wild Pacific salmon populations.
Exercise 1: Data Interpretation Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of ppm—or parts per million. Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water from which the sample was taken; finally, answer the questions below.

In a type three survivorship curve, a very large portion of the cohort is killed within the first few weeks of life (Natural Mortality Lab). C. Chyros and S. hispidus are economically important species as a food source. C. chrysos serves as a source of bait for other fishes. Both the blue runner and planehead file fish species eat plankton and associated matter (Rooker et al.
LAB REPORT: WHAT ARE THE EFFECTS OF THREE DRUGS ON THE BRINE SHRIMP ARTEMIA? JASMIN HERRERA 10-10-2011 COLLEGE PREP BIOLOGY MR. HADSALL PERIOD 2 PROBLEM: How will solutions of nicotine, alcohol, and caffeine affect the swimming rate of Artemia? HYPOTHESIS: * ALCOHOL: I think with the alcohol solution the brine shrimp with speed up the rate at which they are swimming. * CAFFEINE: I think the caffeine solution will affect their swimming by stopping them from swimming around. * NICOTINE: I believe the nicotine will slow down their swimming, and because of this they will die.
Another item pointed to pesticides, fertilizers and road salt as additional contributors to the pollution problem. And even further a New York Times article spoke about the algae blooms resulting from phosphate pollution. The lake has experienced a decline in its fish production attributed to the “dead zone” resulting from algae blooms. Further, the fish caught have ingested plastic and plastic the article argues attracts chemicals like bisphenol A (BPA) a contaminant said to affect the endocrine system. This
