S2 EDEXCEL REVISION NOTES Binomial Distribution Binomial probability distribution is defined as: * P(X=r) = nCr x pn x (1-p)n-r * Distribution is written as: X~B(n‚p) Conditions include: * Fixed number of trials * All trials are independent of one another * Probability of success remains constant * Each trial much have the same two possible outcomes E(X) = np Var(X) = npq [where q = 1 - p] SD(X) = Var (X) = npq To calculate the probabilities:

The purpose of this study is to understand the feeding rate of Daphnia magna. D. magna is a species of Daphnia that belongs to the suborder Cladocera (Ebert‚ 2005). They live in freshwater and feed on small‚ suspended particles in the water. They are filter feeders. Phyllopods‚ which are leaf-like appendages‚ provide a filtering apparatus for the collection of food. These structures beat to produce a constant current of water‚ allowing particles to be filtered by fine setae on the thoracic legs.

Bio Lab: The Effect of Exercise on The Respiratory and Circulatory Systems Ellie Cookson Communication: 2. As the graphs show‚ both breathing rates and pulse rates spike significantly between the resting rates and immediately after exercise. Average breathing rates went from 26.7 breaths/min at sitting rate to 46.4 breaths/min during or immediately after exercise. Pulse rates also increased quite dramatically‚ going from an average of 65 beats/min at rest rate to an average of 100.3 beats/min

Aim: 1) To determine the effects of different salt concentration on the percentage of weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through

DESIGN: Research Question What effect does varying the alcohol concentration of yeast have on its fermentation? Introduction Fermentation is the stage during which most CO2 is produced. When no oxygen is available‚ yeast will switch to an alternate metabolic pathway utilizing sugars for energy and producing‚ primarily‚ CO2 and ethanol. Yeast divides rapidly in this phase‚ reaching its carrying capacity (about 50 million cells/ml) in the wort‚ or must‚ and remains suspended
