Investigating A Rapid Rate Of Groundwater Essay

Answer = The graph demonstrates that as the dissolved oxygen levels increase the fish population will increase. The fish show strong growth from 6ppm to 12ppm dissolved oxygen. As the levels reach 14ppm to 18ppm the have a repeating effect as 6ppm to 12ppm.. With this being said, it shows that fish will show growth progress to a certain level of dissolved oxygen and then level off.

This lab was conducted with the purpose of confirming the trait of homeostasis among goldfish. During the experiment, it was recorded that the fish would increase gill movement when placed in colder water two out of the three trials. However, the results showed no significant difference in gill movement in various temperatures of water. This has very little effect on the broad field of science since our only three trials were performed and may have included human error in the trials.

-02 has an irritating effect in mucous membranes and dries secretions, therefore it is important that a high liter of flow of 02 delivering 35-50% be humidified when administered.

Once the experiment was concluded, aged water was slowly added to the temperature- stressed fish in order to raise the temperature of its water. This helped to return its environment back to normal conditions.

13. Which of the following is not an expected response in a fish to a drop in water temperature?

The dissolved oxygen levels are much higher in this experiment than in the previous experiment.

Undoubtedly, Groundwater plays a significant role in California water supply. During a normal year, 30% of the state 's water supply comes from groundwater. In times of extreme drought, groundwater consumption can rise to 60% or more. Even though groundwater is more evenly distributed, over half of the groundwater is unable to be extracted due to the high pumping cost. The largest groundwater reservoirs are found in the Central Valley, with the majority of the supply existing as runoff that seeps into the aquifer.

and the pulse oximeter reading is at 88% room air, so the physician ordered 2 to 4 L of

Temperature had a direct effect on oxygen consumption of crayfish, Orconectes propinquus. Crayfish acclimated to warm temperature (20 to 25 C) had a mean mass of 8.25g +/- 1.05. Crayfish acclimated to cold temperature (3 to 5 C) had a mean mass of 10.61g +/- 0.77. Oxygen consumption rates of 30-60 minute treatments were used and there was no significant difference between the two different treatments (t=0.48, df=58, P=0.70). The data from 0-30 minutes were not used because the crayfish were disrupted by transportation and the data were not normally distributed. The Q10 value was 1.05, representing that there was full compensation for oxygen consumption for the crayfish at two different acclimated temperatures. The oxygen consumption of crayfish was not affected significantly by two different temperatures (Figure 1).

This lab will be driven by the research question, what is the effect of temperature (at 5oC, 15oC, 25oC, 35oC and 45oC) on the photosynthetic rate (measure of oxygen bubbles over a period of time) of Elodea (pondweed)?

The water in the hot bag was approximately 65° Celsius. We allowed the shrimp to move about for 30 minutes because we had the time. Every 10 minutes we replaced the hot water in the bag with fresh hot water because it was slowly cooling down. After the 30 minutes were up we closed the clamps and removed the hot and cold bags from the tubing and counted the number of shrimp in each section and recorded our results. We did not count any dead shrimp because that condition would obviously not be a condition they could survive in. In this part of the lab we measured the temperature of water from each section and recorded that number also. We did this by simply pouring the water from each section into 4 different test tubes and placing a thermometer in each.

Questions to answer in your lab report. NOTE: some questions pertain to the week 1 exercise, some to week 2, and others to both. How is the amount of temperature variation related to the volume of the water body? How might you measure the speed of temperature change? How would you expect the speed of change to vary with habitat volume? Are water temperatures different than air temperatures? How are they different? Are there any cyclical patterns in the temperature-logged data (“time series”) from Angel? If so, what do you think caused these repeating patterns? Based on the results of this exercise, how might you

-If there is more dissolved oxygen in the water, there will be more fish present in the area the water sample is taking from.

5.) Measure out 20ml of water from 4 different parts of the wetland and place it into four different beakers. Measure the temperature with the thermometer and record the results

For both ponds, the procedures are identical to each other. Submerged the YSI 55 DO Meter about 6 inches into the clear water to take an initial DO measurement at the surface, and did the same thing when it was lowered 2 feet into the water to take initial DO measurement at the bottom. The meter took the DO, % DO Saturation, and temperature at both the surface and the bottom of the pond. Four water samples were taken from the pond and collected in viewing tubes. Used the tube on the left side as a control and in the second tube, the group added Phosver 3 Phosphate Reagent
