小弟LEVEL 5左.... THX= = (原本AIM 5**)


本人為2014 BIO考生今日為4/4/2014
岩岩考完BIOLOGY
心中那團火被撲滅左
份卷...我認輸了
LQ太難了
E1難了(明明準備滿分)
BIOTECH..太 難 了

請問...
有無人 +1?

小弟岩岩反醒左下,發覺我地 PURE BIO 份卷好似無乜點考某幾課^^
EG.  movement( ch.17), respiration , body defense mechanism, molecular genetics
咁同C&B BIO 有咩分別^^?
BIODIVERSITY, ECOSYSTEM, HEART, photosynthesis 都好似無考WO ^^

(我一直都以為呢D先係PURE BIO 最重要, 係必須要識既野 TIM )
點解既 -V-??

各位,吾好意思
小弟有小小燥
請多多包容
請大家投下票
並說下你對今日BIO的
感想去比下意見:

用common sense去諗
你跑馬拉松（42公里）有冇可能全程好似跑100米咁跑？
你慢左既話，個average speed咪慢左囉

記錯左
咁點解有低d running speed?

我填左anaerobic respiration
accumulation of lactid acid > harmful effect
其實我本黎諗住寫埋lower ph > affect the activity of enzyme
不過太急..好似無寫到..............................................................................因為個BIOTECH 用左太多時間T^T!

其實E4難喺邊???  我唔係擾敵，但係佢有啲送分架喎..

其實biotech有咩伏位?
除左gene pool小弟睇唔出...

lactic acid點引致muscle fatigue暫時無人知
科學家只係估accumulation of lactic acid->muscle fatgue->ability of muscle to contract decline
mechanism is unknown

It was once believed that lactic acid build-up was the cause of muscle fatigue.The assumption was lactic acid had a "pickling" effect on muscles, inhibiting their ability to contract. The impact of lactic acid on performance is now uncertain, it may assist or hinder muscle fatigue.
So,answering lactic acid causes muscle fatigue may not be absolutely correct. Marking scheme may not show in this way.

I am wondering if its because
anerobic resp will produce lactic acid, causing muscle fatigue
so it can just be used in short distance running for extra supply of energy for a short time
so 100m runners can use it and their muscles can contract stronger
as for marathon runner, to avoid build up of lactic acid they wont choose to use it until the end of the race so most of the time they use aerobic only
thus when compared with 100m runners who use anerobic+aerobic almost in the whole course of the race they run slower??
