Caffeine is a central nervous system stimulant of the methylxanthine class. It is one of the most worldwide consumed psychoactive substances and it is totally legal. 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

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

Should caffeine be banned for minors? Is caffeine that much of a necessity to minors‚ if so should it be banned? Caffeine is actually a drug. But In our society this drug is considered safe and people don ’t really consider it as a drug. This is because most people drink coffee‚ tea‚ soft drinks‚ and all other things that have caffeine. They use this for the boost of energy in the mornings and to go without drowsiness or fatigue during the day. Kids don ’t really drink coffee which has a lot

different concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day‚ the largest concentration of salt will harm the plants the most. First‚ the plants were purchased and the water was prepared with the salt concentrations. Second‚ the plants were watered each day with the different concentrations of salt. Third‚ the plants’ growth were observed and recorded each
