all. This is why enzymes are crucial to life‚ without it life would not exist on earth. One of the many enzymes that are produced naturally within the body is catalase. In Denham Harman’s free-radical theory of aging‚ it is theorized that cells age as a result of exposure to free radicals and oxidizing agent such as hydrogen peroxide. Catalase is the major line of defense that converts hydrogen peroxide into water and oxygen‚ thus decreasing levels of free radicals in the body. According to an article

Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s

We see here that in order for Egeon to keep his marriage alive he has

the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum. The model was supported by the data using a linear fit with chi-squared value: 0.77429 and an r-square value: 0.99988. This experimental value for gravity agrees well with and is within one standard deviation of the accepted value for this location. I. INTRODUCTION The study of the motion of the simple pendulum provided valuable insights into the gravitational force acting
