We will prove that 2^(n+2)+2^(n+1)+2^n is divisible by 7 using formula to multiply powers with the same base:a^(b) * a^(c) = a^(b+c)Now looking at our expression we can write:2^(n+2) + 2^(n+1) + 2^n = 2^n...

Working class children are more likely to underachieve due to internal and external factors. External factors are the those that are culturally deprived meaning that it is outside of the education system ...

The main difference between the two is that only normal body cells go through it, so for instance your skin cells go trough mitosis whereas MEIOSIS is specifically for sex cells, so for instance for the p...

Saturated fatty acids have no double bonds between the carbon atoms in their carbon chain (the carbon chain is ‘saturated’ with hydrogen). In contrast, unsaturated fatty acids have at least one double bon...

A base triplet (sequence of 3 bases) encodes a single amino acid. The same base triplet codes for the same amino acid in all organisms, meaning that the genetic code is universal. In addition the code is ...
