Intro I am going to do an investigation into what concentration of sucrose solution would cause “Incipient Plasmolysis”. Theory Plasmolysis is the result of a (in particular) plant cell which has lost vast amounts of water. When this happens‚ turgor pressure within the cell has decreased to the point where the cytoplasm of the cell membrane peels away from the cell wall. When this begins to happen it is called Incipient Plasmolysis and when the cytoplasm is almost completely gone it is call “full/complete”

Fieldtrip focus 1. Introduction Hypothesis We know every river starts its journey from its source. In the upper course of the river‚ the channel is at a high above its base level i.e. its mouth. Thus the gradient is high. Due to the height‚ it has a lot of potential energy. So it uses this energy to reach its base level. So the process mainly at work is vertical erosion. Further it has got a lot of interlocking spurs. There is less lateral erosion taking place. So the bed load is composed of

A1-1 Different species of algae are distributed in specific zones on the shore according to their characteristics‚ this is called zonation. For our investigation we are analysing the link between these characteristics and the zones in which each species inhabits. The main algal species present are; Pelvetia canaliculata and Fucus spiralis (Upper shore)‚ Ascophyllum nodosum and Fucus vesiculosus (Middle shore)‚ and Fucus serratus and Laminaria digitata (Lower shore). General Appearance Pelvetia

Some people have the view that the events at Dunkirk in 1940 deserve to be remembered as a triumph for Britain and its people. How far do the sources support or contradict this view? May 1940. Germany had attacked France‚ Belgium and Holland. Within six weeks all three countries had surrendered. Germany’s success lay at the feet of a new and successful war technique: Blitzkrieg. This was the fast and overwhelmingly successful invasion of a country using tanks‚ air craft‚ artillery and infantry all

I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme
