Nik's IGCSE Biology: 2.87 understand the function of the eye in focusing near and distant objects, and in responding to changes in light intensity
http://nikbiology.blogspot.com/2012/02/287-understand-function-of-eye-in.html
A site set up to document my studies in IGCSE Biology; with notes on each objective covered that is necessary for the final IGCSE Examinations. Hope you enjoy! Monday, 6 February 2012. 287 understand the function of the eye in focusing near and distant objects, and in responding to changes in light intensity. When the lens shape is changed to adjust to varying distances of objects, this is known as accommodation. And is how we focus light. The ciliary muscles contract. The ciliary muscles relax. These co...

Frazer is Chemistry: A6 Proton Transfer
http://frazerchemistry.blogspot.com/2011/09/a6-proton-transfer.html
Friday, September 2, 2011. Define acids and alkalis in terms of proton transfer, acids as a source of H. And alkalis a source of OH. Acidity is caused by the presence of H. Ions, these ions form when a chemical dissociates in water. What this means is that the water separates the Chemical i.e. HCl into H. Ions, as shown in the below diagram. To do this the HCl gas is bubbled through the water. It is the presence of these H. Alkalinity is basically the same principle, except instead of dealing with H.

Frazer is Chemistry: Bases
http://frazerchemistry.blogspot.com/2011/09/bases.html
Friday, September 2, 2011. Bases are any Metal. For example copper oxide. What you should know is that all alkalis are bases. Every single one, but as the diagram below should explain, not all bases are alkalis. So what’s the difference between a base and an alkali? Well an alkali is a soluble.
