The plasma membrane surrounds the cytoplasm of living cells‚ physically separating the intracellular components from the extracellular environment. It also plays a role in anchoring the cytoskeleton provide shape to the cell‚ and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The plasma membrane helps maintain homeostasis by diffusion and osmosis. Osmosis is the diffusion of water across a membrane. Diffusion is the process by which molecules

Plasma membranes are selectively permeable. The purpose of this experiment is to reveal how a form of diffusion in a semipermeable membrane works by creating a real life simulation of a semipermeable plasma membrane. This is done by building an imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This

Theme: Male/Female relationships and the role of women * Look at the way Shakespeare explores relationships between men and women in Measure for Measure. Consider how the male characters treat the female characters and in particular‚ how Isabella reacts to Angelo’s proposition When Shakespeare wrote Measure for Measure in approximately 1604‚ society was very sexist towards females and men were seen as the stronger sex‚ however Shakespeare included lots of strong female characters in his plays

Solubility of Carbohydrates ‚ Glucose ‚ Galactose and Lactose . Objective : To determine the relative solubility of glucose ‚ galactose and lactose by measuring their saturation point at the same constant temperature. Principle : With 10g distilled water contained in a beaker ‚ then add small quantities of the carbohydrate being test at a time with constant stirring until no more can dissolve ‚ saturation point is represented at r.t.p.. Test the carbohydrates ‚ glucose ‚ galactose and lactose

ESSAY ‘The structure and importance of the plasma membrane found within and around all cells’ The plasma membrane surrounds all eukaryotic and prokaryotic cells. Eukaryotic cells have membrane bounded organelles whereas prokaryotic cells do not. The plasma membrane forms the boundary between the cell cytoplasm and the environment. Its function are to allow different environments to be established inside and outside the cell. It also controls the movement of substances into and out of the cell.

The many complex characters in the play Measure for Measure allow for much interpretation in readers to occur on what is being measured‚ and what is more of value being measured. Isabella has the option of either saving the life of her brother Claudio‚ who was sentenced for death‚ or give up her chaste‚ which would prevent her from becoming a nun. By ultimately deciding his death was the best option‚ Isabella’s virtue is clear‚ but her commitment to this can result in selfish decisions. Through this

Next select the most appropriate filter for the analysis and then anter it into the light channel or the selector depending on the type of Colorimeter you
