Biology StudyRoom Article - Organs and systems - Gas Exchange A small organism, like an amoeba, has a large surface area : volume ratio, and so it can accomplish all the exchange it needs by simple diffusion across its body surface. However, a large organism, like a mammal, has a much smaller surface area: volume ratio, so it can not accomplish all the exchange it needs in this way ... read complete article	Chemistry Study Room Article - Bonding - Shapes of Molecules How to work out the Shape of a Molecule : It is possible to work out the shape of a small molecule that has a formula XY_n by applying a few simple rules. We will use ammonia as an example to illustrate the idea. Rule 1. First find the number of bonding pairs of electrons in the molecule. The number of bonding pairs of electrons in the molecule NH₃ can be seen in the formula... read complete article

Physics Study Room Article - Mechanics - Speed and Velocity - Constant Motion The best way to imagine a situation in which several physical quantities are changing is by drawing a graph. To picture the behaviour of the speed of an object, we plot the distance (from the top of the equation) on the vertical axis and the time (from the bottom of the equation) on the horizontal axis. The result is something like this ... read complete article	Business StudyRoom Article - Marketing - Market Analysis Market Analysis is a process that seeks to identify and quantify the key features of a market by using a range of Market Research techniques.
