CO2 you use the color changes. Hypothesis: I believe in this experiment the more you exercise then the more CO2 we exhale from our bodies. Material: 2 test tubes Water Bromothymol Blue Straw Graduated Cylinder Marking Pencil Procedures: Pick a Lab partner Label 2 test tubes‚ one A and one B Add 10 ml of water to each test tube using a graduated cylinder Add 8-12 drops of Bromothymol Blue to each tube One of the pair will gently blow on the solution in the test tube A while using the other partner

Introduction Every cell is selectively permeable to different molecules. This type of selectively is caused by a semi-permeable membrane‚ which allows the movement of certain molecules across it. Water exchange can be measured in two ways: RBC osmotic permeability is measured‚ and diffusional water permeability is measured (Benga and Borza 1995). Diffusion is the movement of high concentration to low concentration. The diffusion of water across a permeable membrane is called osmosis. Water concentration

Introduction: Systolic blood pressure‚ the highest pressure in the cardiac cycle‚ measures the pressure in the arteries as the left ventricle contracts. Diastolic blood pressure‚ the lowest pressure in the cardiac cycle‚ measures the pressure in the arteries as the ventricles relax and refill with blood just before the next ventricular contraction. We measure blood pressure using a sphygmomanometer and a stethoscope. To measure the systolic pressure‚ place the blood pressure cuff on the upper arm

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

Lab 2: Animal and Plant Cells Purpose: To examine the differences between single cell and multi cell organisms in terms of Animal and Plant cells. Question: What are the differences between multi and single celled plant and animal organisms? Prediction: Spirogyra Cell: The parts of the spirogyra cell that will be visible under the microscope will be; cell wall‚ cell membrane‚ nucleus‚ chloroplasts‚ vacuole and cytoplasm. Banana Cell: The parts of the banana cell that will be visible

From the experiment‚ the blood glucose concentration for Patient A is 5.6 mmol/L(Refer to Table 1). The blood glucose level for Patient A is normal as 5.6mmol/L is in the normal range. Urine sample from Patient A was tested and it is shown that there was no glucose and sodium present. The results showed that Patient A is healthy and could act as a control in this investigation. Secondly‚ patient B is suspected to suffer from diabetes mellitus. The blood glucose concentration for Patient B is 111mmol/L

In this folio task‚ the impact of drug absorption and blood stream concentration‚ on the human body‚ will be observed. The rate of absorption and clearance of the drug‚ relies on many factors. The drugs blood stream concentration‚ time of administration‚ absorption rate‚ clearance rate and the effect of certain parameters‚ will be calculated. This can be completed through using a surge function‚ calculus (derivatives) and straight line graphs (). Graphing technology on the graphics calculator

ABO Blood Typing Lab Purpose The purpose of this lab is to determine the blood types of four blood samples using Anti-A and Anti-B serums. Hypothesis If the anti-B serum is added to the simulated blood‚ the individuals with blood that is type A or type O will have no effect but it will agglutinate the individuals’ blood that is type B or AB. If the anti-A serum is added to the simulated blood‚ those that have blood type O and B will be unaffected but those with type AB or A will agglutinate.
