This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

The experimental membrane we used in this lab acted as a barrier in which only a small number of molecules can pass through. In this experiment we wanted to show the process of osmosis‚ in which water passes through the aforementioned barrier. Osmosis is critical to life because the process regulates the amount of water in the cell‚ in turn regulates the concentration of all of the molecules and ions within the cell. The hypothesis we tested was that the cell with the higher concentration

1975. This technique is very useful because of its ability to detect a specific DNA sequence from a large amount of DNA ⎯ even from the whole genome. This specific sequence can be found through a combination of two different techniques: Agarose Gel Electrophoresis and Hybridization‚ which is known as Southern Blotting. This technique if performed in three phases: (I) prepare the gel and (II) make the blot‚ (III) hybridize and visualize blot. In phase one‚ the gel is prepared in three steps: (1) chemical

The purpose of the lab was to see how exercise affects homeostasis by measuring a person’s heartbeat‚ breathing rate‚ and sweat while they were exercising. The hypothesis I made was‚ if the volunteer starts to exercise‚ then the body will react by quickening the heart and breath rate as well as sweating to keep homeostasis in the body‚ therefore exercise does affect homeostasis. During the experiment there was some major observations that made the answer to the question clear. As the volunteer exercised

Anatomy & Physiology P2 Wednesday‚ September 19‚ 2012 Heart Rate Response to Baroreceptor Feedback Lab Fundamental Question: Does the body respond to its environment? Testable Question: When the body is in the squat position to normal while the time limit stays the same and how far you squat is the same‚ will the heart rate recover after returning to standing position in 10 seconds? Hypothesis: If the body moves back to normal position from squatting position while the time limit and squat angle

It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

Taylor Hill Lab 6: Enzymes Purpose: The purpose of this lab is to test for enzyme activity‚ look at enzyme specificity‚ and how temperature affects enzyme activity. Hypothesis: I believe that the room temperature activity will produce the most activity. Materials: 3% hydrogen peroxide‚ a household blender‚ potatoes (3 medium size potatoes‚ that are peeled and quartered)‚ tap water‚ 8 test tubes‚ 8 transfer pipets‚ sugar packets‚ salt‚ a small saucepan‚ a refrigerator with a freezer‚ stove

Biology 103 Lab Spring 2013 Does a larger head mean higher intelligence? Introduction: Some say a larger head gives room for a bigger‚ more intelligent brain. Men‚ thought to have larger heads simply because they’re… well men. In which case‚ men have a larger head size than women‚ therefore making men smarter than women. Methods: My partner and I went ahead and measured the heads of 15 people in our class‚ 5 of them male and 10 of them female. We used a measuring band to measure‚ to
