many ‘modern’ societies that still treat women as second-class citizens.

region‚ the suppression of women and allowing them to think and act on their own free will has been part of Samarkand culture for generations. Samarkand by Amin Maalouf accurately shows how during this time‚ women such as Jahan‚ Shireen and even the Sultana were dominated by men. Jahan is probably the most male dominated character in the novel. From her entrance into the novel‚ she is already being subject to humiliation and used to boast male dominance over women. After she recites her poem in

increases in mass will indicate that the water potential of the Beetroot cell is lower than that of the surrounding sucrose solution. The Beetroot discs will become flaccid and decrease in mass if the water potential of the surrounding solution is lower than the water potential inside the beetroot cell. I predict that Osmosis will not occur (at 0% cont.) if the water potential of the sucrose solution (detergent) and the water potential of the cell’s cytoplasm are equal. I also predict that an increase

After realizing the error‚ the assistant randomly labeled the flasks containing these four unknown solutions as flask A‚ flask B‚ flask C‚ and flask D. Design an experiment‚ based on the principles of diffusion and osmosis‚ that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in
