呢條睇書就得啦喎 你唔明邊度

同氮循環搞亂左😂明啦

記得係答more/less proportion of water is absorbed, 冇proportion即收皮

依家最尾呢日仲有咩可以做?
2018-04-05 16:27:02
睇番一次啲pp

天氣咁好,出街行下

The term is out-syl
Only need to know interphase, and the activities taking place in this stage.

Osmosis係要有selectively permeable membrane。Option D嘅講法意味著osmosis唔一定需要有selectively permeable membrane。咁係錯。

唔緊要

要強調係net movement
2018-04-05 16:48:55
即係佢無強調Net movement 既話water molecule可以由低water potential 去高Water potential?
2018-04-05 16:59:40
事實上係有,不過由高去低既water molecule更加多,所以個net effect係由高去低

突然好緊張

all molecules including water molecules have random motion.

but under the conditon with water potential difference between the selectively permeable membrane, people discovered that MORE water molecules actually move from high w.p. to low w.p by the experimental result, so osmosis is a discription of NET movement of water molecules.

睇依個post睇到個人好淆底 感覺好似好多嘢唔識
2018-04-05 17:08:36
係嫁,第一科筆試係咁,之後就冇嘢。
我肯定今晚好多人想訓都訓唔著,甚至越想訓就越訓唔著。
2018-04-05 17:13:23
今晚諗住食返兩粒特強感冒藥再訓
