Neurotransmitters are endogenous chemicals which relay‚ amplify‚ and modulate signals between a neuron and another cell. Chemical messengers must fulfill four criteria to be considered a transmitter. These four steps include the synthesis of a transmitter substance‚ the storage and release of

According to the results‚ there was no significant difference between the filtered 100% water composition‚ and the filtered 90% water 10% soap composition. However‚ based on fFigure 2‚ the Average of Absorbance graph‚ showed that growth of the algae for the 100% water composition was observed to be slightly higher than the 90% water 10% soap composition. Meaning the soap may have slightly affected the growth of the algae‚ in some way. One possible‚ reason for a slightly higher growth for the filtered
