Air Pollution Air is the most important element of life. For some ’air pollution‚’ let us give thanks. Dust and other particles in the atmosphere serve as nuclei about which raindrops form.

In Joseph Conrad’s Heart of Darkness‚ the juxtaposition of light and dark -- in addition to an abundance of imagery-- serves as a vehicle to understanding Conrad’s tainted view of humanity as deeply flawed.

fluorescent light and why ultraviolet light is required to visualise it. (5 marks) When GFP is hit with UV light‚ the chromophore is hit by a photon. This changes the chromophore from ground state (A) to A*‚ which is a highly excitable state. Due to such a highly excitable state not being able to remain so for very long‚ the A* state chromophore emits a proton‚ lowering its state to I*‚ the energetic I. This I* state chromophore lowers its energy by emitting a photon of green light‚ lowering its
