唔使好似數學神算子 講到咁複雜...
係生物裡, differentially permeable既係cell membrane. Boiling 會煲爛d cells, membrane 穿左, 就唔係 differentially permeable , 變成直情係 fully permeable .
就係咁簡單.

首先,differentially permeable membrane係由cell組成既,
而cell係由Protein形成,
而protein係高溫果時,會denature
即係死左咁題意思,
而每一個cell都係differentially permeable
如果佢地死左既話,
就會失去左osmois呢個作用,
亦之所以會變成fully permeable

希望可以幫到你
如果再有唔明,
歡迎再次發問,
多謝你既問題
