Introduction: Heart Rate is defined as the amount of times a person’s heart beats in one minute. A resting heart rate is the person’s heart rate prior to any activity or exercise. As activity increases‚ the heart rate will increase in speed. An increased heart rate is essential as it replaces oxygen in the muscles that is used during said activity and gets rid of excess carbon dioxide through the blood stream. Blood pressure is the force of the blood pushing on the walls of the veins and arteries

In this lab the rate of germination in relation to temperature was observed testing the hypothesis‚ if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray

century that separates Joseph Conrad’s exploration of colonial regime in his novella Heart of Darkness and Edward Zwick’s post-colonial film Blood Diamond‚ the values driving the major characters and factions from the different texts are comparably similar. In both texts‚ there are individuals showcasing major facets motivated by greed‚ obsessed with the stimulus that is presented in either century. In Conrad’s Heart of Darkness‚ the character ‘Kurtz’ is primarily stimulated by greed. His obsession

Every day your heart pumps blood through a vast network of blood vessels around and around your body‚ delivering food and oxygen to cells and removing waste. The pulse (heart rate) is the number of times a person’s heart beats per minute (bpm). The pulse is a rhythmical throbbing of the arteries as blood is propelled through them‚ typically felt in the wrists or neck. Your resting heart rate occurs when you become relaxed or comfortable. These are shown when sitting or lying down. The ability to

Heart rate measurement indicates the soundness of the human cardiovascular system. This project demonstrates a technique to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the blood. It consists of an infrared LED that transmits an IR signal through the fingertip of the subject‚ a part of which is reflected by the blood cells. The reflected signal is detected by a photo diode sensor. The changing blood volume with heartbeat results in a train

Chirped Pulse Fourier Transform Microwave (CP-FTMW) Spectrometer Abstract: Under the condition in which electric and magnetic fields are absent‚ rotational constants is a three molecular constants that substantiate polyatomic molecule. In this laboratory experiment at Missouri University of Science and Technology‚ we are going to collect rotational spectra by using 2 separate types of microwave spectrometers -- the FTMW (Fourier Transform Microwave) spectrometer and CP-FTMW (Chirped Pulse Fourier

Effect of Exercise on Heart Rate. Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Hypothesis: I predict that as I increase the intensity of the exercise I do‚ that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat

The Human Heart Rate Aim: To study changes in the rate of the human heartbeat. Introduction: Blood is sent pulsing through the body’s veins‚ arteries and capillaries with each beat of the heart. The circulation of blood through the body delivers oxygen and food to the cells and removes wastes. The cells cannot survive if circulation stops for even a small amount of time. With an increase in body movement there is an increase in the cell’s energy use and the heart rate must increase to pump

The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of
