To investigate the effect of variation in temperature on the permeability of cell membranes using fresh beetroot Aims In this investigation‚ you will subject fresh‚ washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly

Running Head: Crime and Gambling Gambling can be viewed as the act of risking money (or equivalent) on an uncertain chance of winning a larger amount of money (or some other good). Gambling may involve some element of skill (e.g.‚ poker‚ horse track bets) or be determined by pure chance (e.g.‚ slot machines‚ lotteries) (Turner & Fritz‚ 2007). In nearly all cases‚ the long-term expected result for the player is a loss. Gambling and its link with criminal activity is an area of growing research interest

His mouth‚ running almost the whole length of his head‚ was closed and fixed in that evil bony smile‚ and where the yellow underside came up to it‚ it was tinged with green. From the day‚ perhaps a hundred years ago‚ when the sun had hatched him in a sandbank‚ and he had broken his shell‚ and got his head out and looked around‚ ready to snap at anything before he was even fully hatched—from that day‚ when he had at once made

Practical Assessment Planning AIM Beetroot cells contain a red pigment‚ which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell surrounds it. The outer of the cell is also surrounded by a membrane‚ which again helps contain the pigment inside the cell. In this experiment I aim to find out the relationship between the leakage of red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot

Computer Simulation of Cell Transport Mechanisms and Permeability: Passive Processes and Active Processes Introduction In this lab we will establish a difference between the two types of cell transport mechanisms and their permeability. The first type of cell transport is passive processes which are driven by concentration or pressure differences in the interior and exterior of the cell. The second type is active processes which use energy known as ATP to power the transport. There are two
