This experiment aims to discover the effect of 6 different treatments on the permeability of the cell membrane. These will be distilled water‚ sucrose‚ sodium hydroxide‚ hydrochloric acid‚ ethanol and boiled water. The treatments include immersion in these solutions‚ and exposure to high temperature. The tissue used is from the taproot of a beetroot‚ and the effect on the membrane’s permeability assessed by the amount of pigment leakage that occurs. Hypothesis ==========

Temas and Jerry both show similarities through courage. For their test‚ the both have little to protect themselves. Temas is only given a rawhide shield‚ long spear‚ and a short sword while Jerry only had goggles‚ ability to swim‚ and capability of holding his breath for more than two minutes. Temas and Jerry showed courage because with the shortage of weapons‚ they were still able to complete their test. However their test differed from whether it was official
