Design IA Research Question How Does Increasing the Intensity of Exercise Affect Respiratory Rate? Hypothesis My experiment will involve sprinting which is a very demanding and fatiguing sport. In order to increase the intensity of it‚ I will be increasing the weight the subject has to carry as he sprints. My hypothesis is that as you increase the weight‚ the respiratory rate will also increase. At rest‚ the average breathing rate for adults is 12-24 breaths per minute and for new born babies

Design Research question: This should be a clear focused question that says exactly what you are investigating. It shouldn’t be too long and it must include the dependent and independent variables. Eg. What is the effect of pH on the activity rate of salivary amylase? Dependent variable: activity rate Independent variable: pH Hypothesis: This is a paragraph or two where you explain your research question. You are going to say something like: "Salivary Amylase is a an enzyme that digests

The purpose of this investigation was to see if doing push ups affects one’s heart rate. It was found that the exercise that was performed did affect the heart rate. Therefore‚ doing push ups did increase the heart rate. If doing exercise increases one’s heart rate‚ then doing push ups affects the heart rate. This investigation deals with analyzing the effect on doing an exercise‚ in this case- pushups; will increase one’s heart rate. I have analyzed ten boys between the ages of fifteen and seventeen

How does light intensity affect the rate of photosynthesis? Does the amount of light intensity increase the rate of photosynthesis in a pondweed? Design aspect 1 Introduction My investigation will be centered on measuring the rate of photosynthesis and whether or not light intensity will affect it. The formula of photosynthesis is Carbon dioxide + water oxygen + glucose with the arrow referring to light energy as a means to convert the CO2 and H2O into oxygen and glucose. Logically‚ one would

Sarah Clay Internal Assessment Design Question: Does the caffeine in Coca-Cola affect blood pressure? Hypothesis: The amount of caffeine in Coca-Cola will cause to the adrenal glands‚ located on the top of the kidneys‚ to release more adrenaline which will in turn cause an increase in blood pressure. As the amount of Coca-Cola decreases‚ so will the difference between initial blood pressure and blood pressure after the consumption of the caffeine. Variables: Independent Variables | Dependent

10.1.3 CROSSING OVER Outline the process of crossing over in : Meiosis 1: • Prophase I - homologous chromosomes are paired up tightly into tetrads‚ then crossing over‚ the exchange of genetic material between the DNA in these tetrads occurs‚ forming a chiasmata‚ an x-shaped structure. • Metaphase I - paired chromosomes line up along the equator of a cell‚ the metaphase plate as the spindle microtubulue apparatus pulls them. • Anaphase I - The spindle microtubules pull homologous chromosomes
