Title : The movement of substances across a semi permeable membrane Objective : To study the movement of substances across a semi permeable membrane Problem statement : What factor influences the diffusion of substances through a semi permeable membrane? Hypothesis : The diffusion of molecules across a semi permeable membrane is based on the size of the molecule Variables: a) Manipulated : Size of solute molecules b) Responding : Colour of solution c) Fixed : Temperature and time

Philosopher who lived through the early 1600s and was an essential individual that created the idea concerning “Life‚ Liberty‚ and Property.” The ideas from the Founders’ about government mainly consisted Locke’s writings. 1ST PARAGRAPH - What did Locke think would happen without government? A State of Nature is a society without government or laws. Locke believed when men became overpopulated enough to the point where land becomes scarce‚ then men needed law beyond the natural law. The natural law‚

Proteins and enzymes are also affected by temperature changes. Oxygen is essential for the production of ATP from nutrients in cells; consequently oxygen must be delivered to a cell in sufficient amounts. Within fish‚ the counter-current exchange system allows for the efficient extraction of oxygen from the water by the gills. Basically when a fish takes in water‚ the flow of it is opposite to the flow of blood. As they rush by each other oxygen from the water is given to the blood (metabolic rate is also

The hypothesis was rejected in this experiment‚ based on the results. The results were much different than hypothesized before the experiment. It was hypothesized that the lower concentrations of CLR‚ Jar E and Jar D‚ would be healthier and more likely to reproduce than the higher concentrations of CLR‚ Jar B and C. However‚ as shown in the actual results‚ Jar E and D with the lower concentrations of CLR died quicker than Jar B and C. The CLR and water solutions acted as a fertilizer‚ so the greater
