Tyler Cowan Professor Foltz Biology 181 April 8th 2015 Lab Report: Respiration Abstract: The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control‚ elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of

Reconstructing a Cow’s Knee Lab Objective: To learn the function of the knee and how its ligaments work to create the movement the knee makes by taking apart the knee and reconstructing it with different materials to replace the ligaments. Hypothesis: If we replace the cow’s knee tendons with rubber bands then it will work like a new knee because the rubber bands will provide the support‚ strength‚ and flexibility it needs. Safety: Wear gloves while handling the knee‚ use precaution when

What is the difference between the ocular lens and the objective lens? Ocular lens is the lens you look through and objective lens is the lens that is close to the stage. 3. Where do you place the slide on the microscope? the stage under the stage clips 4. Which adjustment‚ course or fine‚ do you use when you are observing the

Modeling Effective Dose: Salt Tasting lab Purpose The purpose of this lab is to see at what measurements (of salt) can the salt be detected by taste. Abstract The science of toxicology is based on the principle that there is a relationship between a toxic reaction (the response) and the amount of poison received (the dose). An important assumption in this relationship is that there is almost always a dose below which no response occurs or can be measured. A second assumption is that once a maximum

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

Iker Lopez 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

Adwoa Fosuah Bio Psych Lab Report 4 Cold Pressor Task Aim The cold pressor test is done by having the subject submerge their hands in a bucket of cold water to determine cardiovascular changes such as blood pressure and heart rate. For this experiment we wanted to know how long participant can keep their feet in the bucket of ice water before they experience any pain while looking at neutral and positive pictures and also rate the intensity of their pain. For this reason we hypothesized that
