Enzymes Research Enzyme optimum temperature The graph on the left compares enzymes activity with the temperature the enzymes are in. The optimum temperature for enzymes is 40 degrees but anywhere above that temperature the enzymes activity rapidly decreases because the enzymes denatures. Enzyme optimum pH This graph compares

Determining the Solute Concentration of a Potato Aim: In this investigation I am going to work out the sugar concentration of a potato. I aim to find this out by putting potato cores into various concentrations‚ measuring the mass before and after. Due to osmosis the potato cores will change in mass to make the concentrations at an isotonic level‚ helping us to work out the mass of the potato. I predict that potato in the weaker solutions will gain mass‚ because some water will be absorbed by the

Explain the distribution of the world’s major geophysical hazards. Some parts of the world are more often and more severely afflicted by natural hazards than others due to the geological structure of the Earth. The earth’s crust is made up of seven major plates and a number of minor plates. The plates move because of the convection currents in the mantle caused by temperature differences within the mantle‚ leading to volcanoes and earthquakes‚ the world’s major geophysical hazards. The movement

A hazard is a situation that poses a level of threat to life. Volcanoes exist all over the world and countless of them go over without us releasing because they are all of different magnitude. Only 10% of volcanoes are monitored around the world from which 90% of these are located in MEDC’S ( More Economically Developed Countries) Volcanoes can pose different type of hazards separating into primary and secondary. Primary being the ash and dust‚ lava flow‚ volcanic gases and pyroclastic flow. How
