A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…

Box jellyfish Nomenclature "Box jellyfish" and "sea wasp" are common names for the highly venomous Chironex fleckeri. However, these terms are ambiguous, as "sea wasp" and "marine stinger" are sometimes used to refer to other jellyfish.

Carbon is the backbone of life on Earth. All things are made of Carbon. It is a part of the ocean, air and even rocks. This carbon flows between each reservoir in an exchange called the Carbon Cycle. This cycle will be investigated to show an understanding of its functions and how human activity can severely impact this cycle. (insert hypothesis here). Human activity, with out proper regulation can lead to imbalance throughout the carbon cycle meaning the interference of a Global system much…
