x(x+2)>8 if and only if x^2+2x-8>0 if and only if (x+4)(x-2)>0. There are three cases: x<-4, -4 In the first case x+4<0 and x-2<0, so their product is positive: (x+4)(x-2)>0. Next x+4...

DNA is first transcribed into a messenger RNA molecule called mRNA, RNA is similar to DNA but contains Uracil instead of Thymine. RNA polymerase recruits nucleotides to build the mRNA mol...

Since the quadratic has roots a and b, this means it can be fatored as 2(x-a)(x-b)=0. Expanding this out we get 2x^2-2(a+b)x+2ab=0 and matching the coefficients for the terms x^1 and x^0 we get a+b=-4 and...

Diffusion can otherwise be known as the technical term for the movement of particles. It is the process where the particles in question moves from an area where it is high in concentration to an area wher...

There are four DNA nucleotides: Adenine, Cytosine, Thymine and Guanine. They are each made up of a nitrogenous base, deoxyribose sugar, and a phosphate group, and the four nucleotides differ in the struct...
