footballers get paid too much. The average premier league footballer wages have reached £22‚353 a week this is before the ludicrous bonuses this adds up to £1.16million a year!! However it all depends on what you mean by footballer. A footballer could be anyone that plays football‚ so this means that not all footballers even get paid (as a footballer). So ‘Do Footballers Get Paid Too Much’ is a very open to interpretation‚ and doesn’t have a simple yes no answer. Also being a footballer is a very unpredictable

Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can
