(i) 1. amino acid 2. DNA(ii) Decomposer microrganisms break down dead material into ammonia. Ammonia is then converted into nitrite and then oxidised to nitrate by nitrifying bacteria. The process is know...

f(x)=(12x^2)(e^2x) - 14, so using the chain rule f'(x)=(24x)(e^2x) + (12x^2)(2e^2x).To find the turning points set f'(x)=0, so (24x)(e^2x) + (24x^2)(e^2x) = 0. Thus (24xe^2x)(1+x)=0. Thus x=0 or x=-1.

Both are a type of intermolecular forces which means they act between more than 1 molecules. Do not confuse them with intramolecular forces acting within 1 molecule. Lond...

To rationalise a surd means to manipulate a fraction involving terms which are being square rooted so that no term in the denominator is being square rooted. For this example 2/root(x) we multiply the fra...
