that live in the water‚ their oxygen has to be obtained from the water. The amount of oxygen that these organisms can take from the water is hugely dependent on the dissolved oxygen content in the water. The purpose of the two experiments done in this lab was to see the ideal condition to produce the most dissolved oxygen concentration. We approached the challenge of finding the ideal condition by testing two different variables in two different experiments. In the first experiment‚ we tested the different

Laboratory Exercise #2 Pre Lab This lab will teach me how to use a spectrophotometer. The use of the spectrophotometer is to measure the concentration of solute. The solute being measured must be colored and is determined based on the adsorption of light photons on a wavelength. The spectrophotometer uses a beam of light that strikes the diffraction grating that basically forms of prism of light. Then only a specific wavelength of light shines through the spectrophotometer and interacts with

An ECG (electrocardiogram) is a tool used to evaluate the heart’s electrical activity which measures the current produced in the extracellular fluid. Action potentials that occur in the myocardial cells can be detected by electrodes or leads placed at key points on the skin’s surface (reference text book pg. 371) **add figure of a typical EKG trace** The ECG records 5 different waves that correspond with myocardial activity. The first wave is the P wave which occurs in response to atrial depolarization

Date: Title: Effect of Exercise on Pulse and Breathing Rate Aim: To observe the effects of exercise on pulse and breathing rates Materials/ Apparatus: Stopwatch Introduction: Procedure: 1. Perform the experiment in group of 3 persons. 2. Decide beforehand who will count the pulse rate; count the breathing rate and who will perform the exercise. 3. Record the breathing rate and the pulse rate of the individual at rest. 4. The individual will do 100 jumping jacks. 5. The individual will

compare with your prediction? The threshold doesn’t change because after the voltage was simulated the cardiac muscle cells Ca channels opened. You cannot open them anymore or reopen them before depolarization. This is due to the refractory period. 3) Why is it only possible to induce an extrasystole during relaxation? Because cardiac muscle is able to depolarize after repolarization takes place. 4) Explain why wave summation and tetanus are not possible in cardiac muscle tissue. How well did
