and multicellular organisms are linked to cell size and surface area to volume ratio. The experiment for cell size and diffusion was set to see how and how much water can go to the cells. This movement of water is called Osmosis. Osmosis is the movement of water molecules from an area of low concentration (lots of water) to an area of high concentration (little water) through a semi permeable membrane‚ demonstrated in ‘figure 1’. A semi permeable membrane is a membrane that only lets selected molecules

Surface area / Volume ratio Experiment Introduction: The surface area to volume ratio in living organisms is very important. Nutrients and oxygen need to diffuse through the cell membrane and into the cells. Most cells are no longer than 1mm in diameter because small cells enable nutrients and oxygen to diffuse into the cell quickly and allow waste to diffuse out of the cell quickly. If the cells were any bigger than this then it would take too long for the nutrients and oxygen to diffuse into

type of application scanning or imaging human brain activity used a different approach. A study and experiment had been conducted to real subject in obtaining the real time result and brain mapping of the activity in human brain. Electric Capacitance Volume Tomography (ECVT) were used to measure electrical signals generated from human brain activity and reconstruct volumetric image of the brain signal in real time. ECVT is a method for determination of the dielectric permittivity distribution in the

CHAPTER 4 : COST-VOLUME-PROFIT ANALYSIS : A MANAGERIAL PLANNING TOOL SUMMARY Cost-Volume-Profit analysis estimates how changes in costs (both variable and fixed)‚ sales volume‚ and price affect a company’s profit. CVP is a powerful tool for planning and decision making. Operating Income = Total revenue – Total Expense Contribution margin is the difference between sales and variable expense. It is the amount of sales revenue left over after all the variable expenses are covered that can be used

In Parts A and C‚ the relationship between surface area and volume was investigated. Plasticine was formed into a cube and a sphere; both shapes were cut in half. It was found that plasticine volume should not vary‚ two halves have a greater surface area than a whole‚ and cubes have a greater surface area than spheres of the same volume. In Part B‚ the relationship between diffusion and surface area to volume ratio was investigated. Three agar-phenolphthalein-sodium hydroxide cubes of different sizes

Respiratory Rate and Tidal Volume [pic] The total amount of air moved in and out of the lungs each minute (pulmonary ventilation) depends upon 2 factors: size of each breath (tidal volume) and number of breaths/minute (respiratory rate). For example‚ suppose your tidal volume is 500 mL (0.5 liters) and you breathe 15 times/minute. Your pulmonary ventilation = 15 breaths/min x 0.5 L/breath = 7.5 L/min. Pulmonary Ventilation = (Respiratory rate; breaths per minute) x Pulmonary Ventilation

In Echolocation: Volume Control by Amanda Tromans‚ she explains how some animals and machines use sound to locate things instead of using vision like others. For example‚ bats‚ dolphins‚ and submarines all do this but with a few differences. This paper is more like a review so it does not show specific steps. She explains in the beginning why those exactly use echolocation; this is basically the use of echoes and soundwaves. Those echoes and soundwaves are bounced off many objects so they can get
