1) What patterns do you observe based on the information in table 4?
The information that I observed based on the information given in table 4 was in the number of fish observed. The number of fish observed increased two fish or more over the dissolved oxygen parts per million. But then when fifteen fish seen it then decreased down to ten then started escalating once more.
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.
My personal hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water would be: If the dissolved oxygen continues to increase by two then the number of fish will decrease.
3) What would your experimental approach be to test this hypotheses?
My experimental approach to test my hypotheses would be to continue to increase the dissolved oxygen in units of part per million and observe to see how many fish I see.
4) What would be the independent and dependent variables?
The independent variable of my experiment would be the part per million of the dissolved oxygen. The dependent variable of my experiment would be the number of fish I observe.
5) What would be your control?
The control in my experiment would be the location. I would go to where the experiment took place so that my data would work well with the previous data so that I am able to compare the two together. This will help me know if my hypotheses is in fact true or not.
6) What type of graph would be appropriate for this data?
I believe that a line graph would be appropriate for this data. I chose line graph so that it would be easier to show the data of the two experiments together.
7) Graph the data from table 4: Water Quality vs. Fish Population (Found at the beginning of this exercise). I could not bring up a graph to show but I did in fact draw it.
8) Interpret the data from the graph made in question seven.
The graph I chose to draw was a bar graph. On the left hand side of the graph I numbered it 1-15 in order to show the number of fish observed. On the bottom of the graph was the dissolved oxygen in ppm’s counted by twos starting with zero then two up to eighteen. The indicated that an increase of 12 ppm’s of fish were observed then decreased down to 14 ppm’s and once again starts to increase.
Now for the math part of this assignment.

Exercise 1: Data Analysis

Data Interpretation Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organisms 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 (parts per million). A researcher has found ten bodies of water with incrementally increasing dissolved oxygen and decides to use these to examine the effect dissolved oxygen has on a certain population…

Experiment To Testing The Acidity Of The Rain Water In Lawrence

Abstract: The experiment is to test the acidity of the rain water in Lawrence. In order to conduct the experiment rain water is needed. Litmus paper will be dipped in it and a LaMotte pH Tablet will be dissolved into it. The hypothesis generated for this experiment is that the acidity of the rain water in Lawrence will be between pH levels 4.5 and 5.5. The results showed that there is no acidity in the rain water; in fact it was basic with a pH level of 8. The results happened because the air in…

Specific Metabolic Rate Lab Report

effects of exercise on the specific metabolic rate of three different Pocambarus sp., a species of crayfish. During metabolism, oxygen or O2 plays a big role in receiving electrons at the end of an electron transport chain. These electrons are then transported down the chain where they give off energy to convert low-energy ADP to high-energy ATP. By increasing the need of oxygen as well as the usage of energy in the Pocambarus sp., it would result in the uptake of O2 to increase. Due to this, we hypothesized…

needs oxygen in order to function. Without enough of it, it is impossible to keep up with the energy demands that are required to keep the body alive. In order keep up with this demand, the respiratory centers in the brain will tell the body to breathe. If doing exercise, the demand for oxygen is higher, so more breathing must be done. Carbon dioxide is a waste product of metabolism when oxygen is used, so must be removed from the body. The body does this by exhaling breaths and just like oxygen needed…
