Science: Abstract: This investigation is to show the raspatory and circulatory systems in deeper meaning. It also explains the reasons for why breathing and heart rate becomes higher during physical activity‚ and if there are any differences between female and males. This experiment shows the biological principles‚ and how to record and produce data of a quality standard. Introduction: Air goes into the alveoli when we breathe in. This lets the veins around the alveoli drop of their carbon dioxide

Determining the Effect of Arousal on the Heart Rate and Blood Pressure of Adolescent Males Wyatt Griffith and Michaela Rodriguez Wood River High School Hailey‚ ID 83333 ABSTRACT When male adolescents were unknowingly placed in an isolated environment with an attractive woman‚ there wasn’t enough viable data to determine whether or not their blood pressure increased. Based on our limited and unreliable data there is no significant increase in the heart rate or blood pressure of male adolescents

1. The independent variable for A‚ B‚ and C is postnatal age in hours. The dependent variables for A‚ B‚ and C are systolic blood pressure‚ diastolic blood pressure‚ and mean blood pressure respectively. The relationships between these variable is direct and positive in that as the independent variable of postnatal age increases the corresponding dependent variable increases. 2. The independent and dependent variables in Figure 3 are the same as in Figure 2‚ as well as the relationship between

Is this r value significant? Provide a rationale for your answer. ANSWER: The obligatory r value is -0.149 and this r value is not significant since the p-value for this correlation coefficient or r is 0.424 which is extra than 0.05 or 0.01 and henceforth at

Chemistry Lab Report (Design) Factors affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to

Design lab for the rate of reaction between Mg and H2SO4 Introduction: Increasing the concentration (in moles) of H2SO4 will increase the rate of the reaction when a ribbon of Mg is added to the solution. The rate of the reaction all depends on how strong the concentration of the solution is. Research question: Does altering the concentration of H2SO4 increase the rate of reaction when a ribbon of Mg is mixed with the solution? Variables: Independent Variable: The concentration of

as exercise began‚ the blood with the oxygen immediately went to parts of the body that was doing the work (here‚ the legs). At the initial stage of excercise‚ the subjects actually felt more distracted because of the lack of oxygen in their brain. Also the body had to warm up and get used to running. Once oxygen reached these certain sites‚ the heart continued to pump blood to the rest of the body (including the brain). This was evident towards the end when two of the three subjects’ mathematical
