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

b.) The mass decreased or increased in each cylinder‚ depending on if the solution was hypotonic‚ hypertonic or isotonic. In Cylinder (A) the mass decreased‚ so liquid was released from the potato‚ because the cells in the potato would have burst if even more was absorbed‚ whereas the length stayed the same. In Cylinder (B) the mass and length increased‚ which means the potato cells absorbed some Sodium Chloride (NaCl)‚ so the cells don’t shrivel up and die. For Cylinder 3 the mass and length also

Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly

Romeo and Juliet essay In Romeo and Juliet we learn how Shakespeare uses vivid language to build character and depth in their roles. Shakespeare was a poet‚ playwright and an actor with a great love for language. Shakespeare was of great importance when it came down to the moulding and developing of the English language. Shakespeare had such an immense love for language that he created neologisms that we use in everyday life. Some of these neologisms he created include words such as puke‚ lonely

2.) a) proteins b.) i) Amylase ii) Protease iii) Lipase c) i) Glucose ii) Amino Acids iii) Fatty acids and Glycerol 3.) a.) Each enzyme has a unique shape that fits onto the substrate. As enzymes normally only catalyse one reaction the substrate has to fit in the specific shape (active site) and if it doesn’t fit in (lock and key method) then the enzyme won’t be catalysed. b.) As when the enzyme is denatured it’s special shape is destroyed‚ thus destroying it’s active site meaning that

My hospital bed was ice cold and the bleak and empty white walls depressed me as the uncomforting thought that I would have to stay here for maybe another week brought tears to my eyes. The usual and oppressive smell of disinfectant lingered in the room as I recalled that night in my head‚ trying to convince myself it wasn’t my fault‚ as I had done everyday since the accident. It was the day everything changed and my life was turned upside down. Forever. Provocatively decorated caravans snaked to

Latin – Grammar The Genitive Case The genitive case is most often used to give possession‚ i.e. ‘of’. For example‚ ‘portus Alexandriae’ means ‘the port of Alexandria”. Portus = nominative singular‚ Alexandriae = genitive singular. However‚ the genitive case is also used in two other ways: the partitive genitive and the genitive of description. The Partitive Genitive This is used to show a part of a whole‚ mostly used in relation to quantity. Nominative(but the case changes) | + Genitive |
