Aim: The aim of the experiment that was carried out was to see‚ at what temperature and in which standard solution‚ does the amount of dye left in the boiling tube had the highest percentage transmission. Beetroot was used for the experiment because it was easier to see the dye after the practical was completed. Putting beetroot cylinders into different boiling tubes‚ which contained

Brownian motion This is‚ presumably the random drifting of particles suspended in a fluid (a liquid or a gas) .This movement was discovered and later named after botanist Robert Brown (1773-1858). He was a Scottish botanist and palaeobotanist who made important contributions (including Brownian motion) to botany largely through his pioneering use of the microscope. The scientist who made Brownian motion famous is Albert Einstein‚ who brought the phenomenon to the attention of the larger physics community

surroundings‚ it tries to make concentration of solution inside and outside itself equal. However‚ the solutes are too big to pass the cell membranes without the help of channel proteins‚ or transport proteins. Water may freely pass through the membrane by osmosis‚ which requires no energy. Thus‚ the cell starts to take in‚ or release‚ water until it is isotionic to its

Avianus and Caxton tell different stories of a goose that lays a golden egg‚ where other versions have a hen‚ as in Townsend: "A cottager and his wife had a Hen that laid a golden egg every day. They supposed that the Hen must contain a great lump of gold in its inside‚ and in order to get the gold they killed it. Having done so‚ they found to their surprise that the Hen differed in no respect from their other hens. The foolish pair‚ thus hoping to become rich all at once‚ deprived themselves of

Shell - less egg is placed into a beaker of corn syrup‚ will there be any water going into or out of the egg and if the shell - less egg is placed in a beaker of distilled water will be any net flow of water going into or out of the egg. Hypothesis: If a shell - less egg is placed into a beaker of corn syrup solution‚ then there will be a net flow of water going into the egg because the water molecules will be small enough to pass through the membrane of the egg. If a shell - less egg is placed

Introduction A computerized simulation experiment will be conducted in order to study the cell transport mechanism via the cell’s selectively permeable membrane and passive processes of simple and facilitated diffusion. The plasma membrane is a gateway which allows nutrients to enter the cell and keep undesirable substances out‚ hence‚ making it selectively permeable. One method of transport is called active transport‚ which uses ATP to transport substances through the membrane. The other is

Joanna Packham ENG 111 Reverse Osmosis in Our Life My husband and I installed a reverse osmosis drinking water system in our home. I have traveled a lot recently and met lots of people including engineers on the yachts that thought me a lot abut reverse osmosis systems. They explained to me that RO are declining in popularity because they remove the minerals as well the impurities from the water. Long-term consumption of filtered water had negative health effects. I was asking myself is RO water

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable
