Investigation - Solution Colour and Ion Concentration Aim: To investigate whether solution colour can be used to reliably determine the concentration of coloured ions in a solution. Hypothesis: the concentration of permanganate ions in the solution is inversely proportional to the percentage transmission of light through the solution. Dependent variable: concentration of permanganate ions. Independent variable: percentage transmission of light through the solution. Equipment: 20 ml

2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

A zoologist and geneticist named Thomas Hunt Morgan is known for his research with fruit fly. Thomas Morgan was born on September 15‚1866 in Lexington‚ Kentucky. In 1886‚ he received his B.S. degree at the University of Kentucky. In 1910‚ Morgan saw that one male fly had a distinct difference about it. Instead of normal red eyes‚ this fly had white eyes (Allen). He wanted to test the breeding of Drosophila in fruit flies to understand the transmission of genetic traits through their generations. In

As Jeanette‚ the protagonist of Jeanette Winterson’s Oranges Are Not the Only Fruit‚ states‚ “time is a great deadener.” (93) Essentially‚ as time passes‚ people will inherently forget crucial details of history‚ allowing for various interpretations and even inaccuracies to be perpetuated. The aforementioned Oranges‚ Kurt Vonnegut’s Slaughterhouse Five‚ Tom Stoppard’s play Arcadia‚ and Chinua Achebe’s Things Fall Apart all explore‚ in some capacity‚ how certain people or events from the past are
Premium Edgar Allan Poe Short story The Tell-Tale Heart
On the surface of the novel‚ Oranges Are Not The Only Fruit‚ may appear to be about a young lady trying to figure out who she is whilst in a constrained community. However this is not the whole story. Within the novel there are constant struggles with finding who you are‚ social class and the broad concept of fitting in. Winterson does this well through her use of symbols and motifs which are as one example an orange. Even the sub-plots within the novel such as her mother possibly having a lesbian

Forbidden Fruit Daniel Ayton stood at the end of the aisle‚ fiddling with the hem of his tuxedo jacket‚ feeling more and more nervous as the seconds ticked by. Normally‚ people staring at him didn’t bother him‚ he was used to it and actually enjoyed the attention‚ but today... today was different. Today everyone’s eyes would be on him‚ expecting him to say all the right things without breaking down. He tried to suppress the anxiety that was blossoming in his stomach and threatening to push through

Oranges Are Not the Only Fruit: very clear on Winterson’s own perspective and opinion‚ conveyed through her own history as the protagonist and the structure of the novel. POST MODERNISM - fragmented‚ discontinuous structure‚ hybrids‚ experimenting‚ and subjective view of truth. Post modernism came about because of the first world war- left Britain broken and fragmented. The massive blood bath changed the mind-set of the country‚ thought about bigger questions‚ ideas about rejecting an overall authority

System I: Ion Channels 1. What structures in the cell membrane function as ion channels? Integral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? 1. Charge 2. Size 3. Amount of water the ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an __________nongated______________ channel. 4. Would sodium ions move into

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is‚ we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into or (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)
