10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by

Though they‚ frequently have a big audience‚ their contents are quite superficial and in poor taste. In addition

Fan Cart Lab We did a fan cart for our physics class the other day. To set up the lab first‚ we measured the effect of the mass of the fan cart on the acceleration of the cart. The mass of the fan cart was the independent variable and acceleration was the dependent variable. We kept the speed of the cart on medium‚ and calculated the acceleration and motion. As a result‚ we had figured out that the bigger the mass the slower the acceleration‚ as we all should have known. To calculate this we used

One size doesn’t fit all. Many companies find that the best way to get ahead is to expand ownership boundaries through mergers and acquisitions. For others‚ separating the public ownership of a subsidiary or business segment offers more advantages.
