Resistance is due to the collision of free electrons with the metal ions of the conductor. When the temperture increases, the metal ions have more energy and vibrate. This increases the frequency of colli...

f(x) = 3x^3 + 2x^2 - 8x + 4

f(2) = 3(2)^3 + 2(2)^2 - 8(2) + 4

f(2) = 3(8) + 2(4) - 8(2) + 4

f(2) = 24 + 8 - 16 +4

f(2) = 20

Vertical transmission occurs during asexual reproduction. During the cell cycle, a bacterium will replicate its DNA (found in the form of a circular plasmid) which will contain the gene for antibiotic res...

a) By simple parametric differentiation of each term, dy/dx = 2x^2 + 2x b) The condition for a turning point is the gradient (dy/dx) at that point is zero. 0 = x(2x + 2) so either x=0 or 2x+2=0. Therefore...

Tsar Nicholas II's abdication came against a backdrop of a changing political, social and religious nation but the catalyst for change came through Russia's struggles in the First World War. Nicholas was ...
