經過近曲小管時會進行重吸收部份溶質被近曲小管吸收流體水勢上升因此水同時藉滲透進入近曲小管壁咁岩一樣比例因此無變化

有無人記得why protection level of JE suddenly rise in paper 1B 個題幾分同應該點答

好似四分
first injection
memory cells are produced

second injection
memory cell recognize the antigen

secondary immune response
large amount of Plasma cells are produced in short time to produce antibodies .
Also large amount of killer T cells are produced to kill the pathogens directly.

唔太記得,大約係咁

我寫first exposure to antigen of JE, memory cells are produced. When second exposure to antigen of JE , memory cells remember and recognise the antigen, this produces larger amount of antibodies, killer T cells , plasma cells and memory cells in shorter period of time. 有無問題
