    The size of the surface must also be large enough to allow sufficient molecules to be transported to accommodate the metabolic processes in cell. For this reason, the surface area to volume ratio for any cell is critical. Size is also important in terms of width and length of a surface carrying out transport of materials. For example; the surface area of single-called alveoli in a person’s lungs, if spread out flat on a surface, would total the area of a football pitch.…

    Introduction: The biological membranes are composed of phospholipid bilayers, each phospholipid with hydrophilic heads and hydrophobic tails, and proteins. This arrangement of the proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained within cells, but water is perhaps the single most important molecule in any living system (Hayden and McNeil 2012). Since water molecules are so small, they are constantly going into and out of the cell. Osmosis is a situation where more water molecules are moving across the membrane in one direction than the other (Hayden and McNeil 2012). During osmosis the net movement of water molecules will be from a solution that has a lower osmotic concentration to a solution that has a higher osmotic concentration. When a solution has a higher concentration of solute within the cell than out, it is called hypertonic. When a solution has a lower concentration of solute within the cell than out, it is called hypotonic. And when there are equal concentrations inside and out of the cell, it is called isotonic. The relative osmotic concentration can be determined by a change in mass of the tissue.…

    A new drug has been formulated to reduce hyperactivity for children ages 5-17. To test this I will be using 100 children that are randomly selected clinically labeled hyperactive child. 50 Children will be randomly assigned to the experimental group and the others will be placed in the control group. Both groups however will be told that they are being given the new drug (a single – blind study). The experimental group will be given the drug and will be asked to meet every day for two hours, at a designated location and will be observed on how they behave, with regard to the environment their being placed in is an applicable place to do their homework/read etc. The control group will be given a placebo and asked to meet together daily, for the same amount of time (but at a different location). The independent variable is the new drug and the dependent variable will be how the hyperactivity in the children changes (whether increasing or decreasing). Both the experimental group and the control group will be observed by 10 other psychologist and at the end of the trial period (2 weeks), we will hear what they have to say on the 5 children that they each observed. An average will be totaled of how many hyperactive bursts each of the children (from both groups) make. Inferential statistics will then be used from the averages (along with the other data from the experiment) to see how the results would be, dealing with a larger…
