Firstly, improved monitoring of volcanoes can reduce the death toll of an eruption by leading to enhanced predictions of hazard events and thus providing a longer period for the evacuation of vulnerable i...

log2(x + 3) + log2(x - 3) = 4log2 [(x + 3)(x - 3)] = 4x^2 - 9 = 16x^2 = 25x = 5

The transition metals have five distinct orbitals in their third energy level. When bonded to a ligand these orbitals are separated into two groups located at two slightly different energy levels. The dif...

Transpiration is the water loss from the plant via evaporation. The transpiration stream is the flow of water through the plant xylem from the roots to the leaves of the plant. Xylem are thin tubes where ...
