The chemical name of caffeine is 1‚ 3‚ 7 – Trimethylpurine – 2‚ 6‚ - dione. Its molecular formula is C8H10N4O2 and it has a molecular mass of 194.19 g/mole. Caffeine is an odourless‚ white crystalline purine‚ a methylxanthine alkaloid‚ which is closely chemically related to adenine and guanine. Caffeine acts through multiple mechanisms

Simple random sample (SRS) In statistics‚ a simple random sample from a population is a sample chosen randomly‚ so that each possible sample has the same probability of being chosen. One consequence is that each member of the population has the same probability of being chosen as any other. In small populations such sampling is typically done "without replacement"‚ i.e.‚ one deliberately avoids choosing any member of the population more than once. Although simple random sampling can be conducted

According to the results‚ the experimental group had a huge impact when the diluted concentration of caffeine was put in compared to the control group that contained no concentration of caffeine. The hypothesis was supported because a significant decrease of the total number of cells when caffeine solution was added to the experimental group was clearly shown. An addition of small amounts of caffeine does inhibit cell proliferation and affect cell viability during the lab experimentation one more test

Caffeine had already existed in the leaf itself but needed to be separated from the other chemicals. Caffeine’s chemical structure is relatively similar to the nucleic acid purine in that they use nitrogen and is bicyclic but lacks an alkene‚ amine and an amide. Caffeine has a solubility of 67.0 g/100 mL in boiling water but tannins also boil in hot water to form catechin. Catechin cannot

10.1 HSC Topic One – The Global Economy Investigate the global distribution of income and wealth-- When analysing the specific distribution of wealth and income at a global level‚ the frequency of the term ‘Inequality’ is quite often brought to attention. This is simply because (and as expanded upon below) the distribution of wealth is anything but equal. To present a proverb or maxim of sorts‚ “The rich continue getting richer‚ while the poor; poorer”‚ generally summing up the current state
