Aim How temperature affects membranes: investigating the effect temperature has on Beta vulgaris membranes when submerged in a range of different temperatures for one minute. Background Information A cell membrane is made up of a phospholipid bilayer formed by phospholipids that have a hydrophilic head and a hydrophobic tail. The phospholipids arrange themselves in order that the heads are exposed to water and the tails are not thus forming the bilayer. When the temperature increases molecules

There are many factors that affect the rate of reaction of bromelain on jello‚ these include pH‚ temperature and substrate concentration. In this demonstration‚ we were able to assess the effect of substrate concentration of pineapple (Containing bromelain) on jello. Our results showed that the relationship between rate of reaction and the change in mass of the jello is proportional. This can be seen that the higher the change in mass of jello‚ it would demonstrate a higher reaction rate‚ as the

Research Question How does the mass of the sandbag affect the amount of time the parachute takes to hit the ground? Hypothesis I predict that if the sandbag is lighter‚ the more time it will take for the parachute to reach the ground. The sail provides a drag pulling upwards to decrease the gravitational force that makes the sandbag fall‚ which is the mass times gravity. Thus‚ the lighter the sandbag‚ the less force there is pulling it downwards and‚ as a result‚ it travels slower and takes
