    however‚ the 5% salt concentration did not result in the least weight gain (g). Table 1 clearly highlights that the 3% salt concentration resulted in the least weight gain (g). The distilled water resulted in the most weight gain (g) because the solution is hypotonic – a hypotonic solution results in the water diffusing into the cell because the molecules of the substance are moving from an area of higher concentration (outside of the cell) to an area of lower concentration (inside the cell) (Hammel

    Earth .” Synder‚ Daly and Bruns have recently proposed that caffeine affects behavior by countering the activity in the human brain of a naturally occurring chemical called adenosine. Adenosine normally depresses neuron firing in many areas of the brain. It apparently does this by inhibiting the release of neurotransmitters‚ chemicals that carry nerve impulses from one neuron to the next. Like many other agents that affect neuron firing‚ adenosine must first bind to specific receptors on neuronal
