痴痴地之下講嘅嘢都幾entertaining 粒seed有腸，我呆下呆下都笑咗出聲

今年e1係咪低機會出kidney
好似出左好多次
好似出左好多次peristalsis 係由muscle contraction 而黎?
pancreatic juice 同bile juice 同一條duct 出?

ii) rbc is responsible for transporting O2
The lack of mitochondria in rbc showing that no oxidative phosphorylaion is taken place in rbc
Therefore, no O2 would be consumed, the amount of O2 transported by rbc wont be affected

好啦已經1：20，依家唔再post題目同回答大家，因為唔想鼓勵大家遲訓。聽朝再post。
明白大家都係緊張嘅，但都應該要知道早睡早起嘅重要性。

axon 去dendron 之間叫synaptic cleft , axon 去muscle cell 之間都係一樣名?
peristalsis係alternate contraction and relaxation of circular and longitudinal muscles
bile 係bile duct，pancreatic juice係pancreatic duct...
bile 係bile duct，pancreatic juice係pancreatic duct...
但有條題目話bile duct 塞住左，叫我答點解食完lipid food會痛，之後第二條就問我點解個pancrea 會自己digest 自己
有冇題目睇下
返到屋企先，睇緊醫生
pancreas係由proteins做成
塞左嗰條應該係pancreatic duct？
pancreas整出黎既protease冇得transport去small intestine 所以就accumulate喺pancreas自己digest自己

take care咁夜睇醫生
急症？
急症？比呀sir呃左去做曬
索warm moist air 對一個低溫環境嘅人黎講有咩好
我除左諗到more water dissolve in water film 之外就諗唔到

Explain how ploughing increase the nitrogen content of the soil (4 marks)
ploughing leads to increase in soil seperation thus oxygen gas and nitrogen gas content in soil also increased
Therefore, more oxygen can provided for nitrogen-fixing bateria undergo nitrogen fixation to convert ammonium compound and nitrite into nitrate .Nitrate stay in soil until plant uptake for protein synthesis.
So ploughing lead to increase in nitrogen content in soil
小試睇下有幾多分，呢種e2我平時4分得1分

有無巴打答下第三題
marking :Adding lipase solution,sodium carbonate,bile salt,oil and phenolphthalein into a test tube,and mix well(1)
Prepare another mixture with bile salt replaced by distilled water as a control (1)
The mixture containing bile salts would take a shorter time to be decolorized than the control (1)
無話有distilled water ,但可以既話即係可以係其他無話有distilled water ge experiment 用都得?
Neuromuscular junction
整一個experimental setup嘅同時就要整多一個做control 我覺得唔落水都得 不過好多時候做experiment普遍都assume你可以無限用正常野 (水,容器)
