Explanation:

students noticed that the potato stick with the lowest mass was soft and floppy. Explain why the potato stick had become soft and floppy.

Explanation:

1. 1.0 (mol dm–3 sodium chloride solution) ;

2.(to remove) excess / surface/AW, water/AW, on potato sticks ;

to measure the mass of the potato (stick) only ;

3.cells / potato sticks, have lost water (by osmosis) ;

from high water potential to low water potential/down water potential

gradient ;

(cells / tissue/ potato) were, plasmolysed/ flaccid ;

loss of turgor (pressure) ;

not enough pressure of water pushing on cell walls ;

4. protein denatured (when cooked) ;

cell membrane, damaged/destroyed (when cooked) ;

no osmosis will occur ;

the real answer is b. scintillation counter
