We need to solve this so we have a positive x term on one side. First we can subtract 3 from both sides of the inequality to get: 5x<3x-9 Next we can subtract 3x from both sides to get: 2x<-9 Finally w...

We need to factorise this equation to solve it. The first step for factorisation is to make the equation equal to zero. We can do this by subtracting x from both sides to get: x²-x-6=0 The coefficent in fron...

DNA or DeoxyriboNucleic Acid, is a nucleic acid made of two polynulcleotide strands (double stranded). These polynucleotide strands consist of a phosphate group, five-carbon sugar (stable 2-deoxyribose) and ...

We will use diagrams to show this in the interactive lesson space - and also run through what key terms the examiners will look for. As with a lot of physical geography, the key thing to learn is the sequenc...

There are two types of enzyme inhibition: competitive and non-competitive. Competitive inhibition: This occurs when an enzyme's active site is filled by an inhibitor. The inhibitor will have a complementary ...
