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

balanced diet and exercise. Obesity rates among children and adults can and will be reduced with proper care of the body. Obesity is when an individual has an excess amount of total body fat. Obesity happens when a person’s calorie intake exceeds the amount of calories used within the body. These excess calories are stored as body fat in the individual‚ which leads to excessive weight gain. There are a number of factors that contribute to the fast rising obesity rate. First‚ there has been a dietary

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

respiratory system. I predict that whilst carrying out the exercise‚ the breathing rate will considerably increase from resting to working breathing rate. However due to the fitness of the volunteer this breathing rate could be different. As soon as the volunteer has stopped the exercise‚ I predict that the breathing rate will steadily decrease over a number of minutes until it gets back to resting breathing rate. I can justify my prediction as throughout the exercise the oxygen requirement will

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They

Emmanuela Kubari Period 2 IB Biology SL Cinematic Suspense on the Heart Rate Research question: What is the effect of suspenseful movie scenes from Jaw on the Heart Rate Hypothesis: Suspenseful movies tend to trigger emotional release because films tend to transmit ideas through emotions rather than through intellect. It is an interesting thing to consider‚ given the fact that the person is just sitting there watching images. Therefore‚ it is surprising to see the effects that suspense has on the

What happened to the R-R interval and heart rate after exercise? After exercise the R-R interval increased steadily from 0.48 to 0.68 seconds‚ while the heart rate BPM decreased steadily from 123 to 76; both trending back towards the resting values. What happened to the T-P interval during exercise? Outline what this means for ventricular filling time. During exercise there was a significant drop in the T-P interval which then steadily increased when exercise was completed. The T-P interval represents

Aerobic metabolism‚ uses fats‚ proteins and carbohydrates that are oxidized and turned into carbon dioxide and water. Anaerobic metabolism‚ uses only carbohydrates and enters the fluid‚ or cytoplasm‚ of the cell and is turned into lactic acid. Aerobic exercises are running‚ biking‚ and swimming‚ whereas anaerobic exercises are sprinting‚ jumping‚ weight training. 3. My activity is considered
