at a specific interval to give a range of varying speeds; these speeds could then be compared to the set speed limit on the road. The purpose of this experiment was to determine if cars on Woody Hayes Drive needed additional traffic control to reduce speeding. The sections that follow describe the process‚ calculations and answers to this experiment. Section 2 will describe the tools and step-by-step processes that’re required to replicate this study.

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

molecules present. This will therefore make the experiment unfair‚ because the more pigment molecules present the more pigment molecules that can move out of the cell. Therefore the beetroot used should be freshly cut. pH The pH is also an important factor‚ as pH can have an effect on the weak interactions and bonds that bound the membrane together. To keep the pH constant it is important to make sure that the same surrounding are used for the experiment. Surface area. The surface area of the beta

In contrast‚ heart rate is increased by the sympathetic nervous system (neurotransmitter: noradrenaline) and the hormone adrenaline circulating in the blood via activation of cell surface receptors in the sinoatrial node - pacemaker) (called beta-1 adrenoceptors). This occurs during exercise or fear. The effect is to increase the rate of ejection of blood by the heart. This means that there will be more blood flow to skeletal muscle (in which exercise causes dilatation of blood vessels)‚ so the

Assignment: Do sports drinks really work? Question... How do sports drinks affect muscle reaction time? Hypothesis My hypothesis is if sport drinks are consumed‚ then the reaction rate will improve. Sport drinks provide individuals with the required amount of water‚ carbohydrates and electrolytes (sodium and potassium) which is lost in sweat while exercising. Maintaining adequate electrolyte levels will enable better cell function‚ which is needed for muscle endurance‚ among other bodily capabilities

Objective In this experiment the purpose is to study the period of the pendulum with different masses. Secondly to also study the relationship in the different lengths of the string and how it affects the period. Thirdly to find the different (time) periods in the changes in the arc size. Theory If the pendulum is set ‚ the force of the motion is used to swing back and forth . where the t period is the time the pendulum takes to complete a cycle of oscillation. As t-1/f the complete distance of

Psychology Experiment No. 2 Effect of Inconsistency of Objects in Scenario on Perception Introduction: In our everyday lives‚ we are used to seeing objects within their particular characteristic scenarios. For example‚ it is nothing to wonder if we see a person browsing the internet in a computer lab or a car speeding on a road. However‚ when we see an object which is inconsistent with the environmental setting‚ we do feel alarmed. Thus‚ it is shocking for us to see someone working on a

The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific
