題目問show how rate of photosynthesis is only dependent on light intensity
-> 佢暗示佢覺得light intensity 係呢個裝置下唔係only variable
-> 所以先叫你show how to modify

至於bicarbonate sol
-> yes same concentration of sol used
-> it can "speed up the rate"
-> 但你地咁做就assume呢個裝置下light intensity is the only variable
-> which is not what q asked

Arround 30% offspring has tongue rolling 個條 係咪doesnt support above conclusion

Yes

應該又係差唔多

E1錯到七彩 E4完全唔識
Paper1又做唔哂人生已完

Mc Q4 已經唔識

4個都岩,但C個目的係顯示denature ge enzyme唔會有反應,而唔係話enzyme會denature

我啲fd話a 因為支野boil左

成個實驗description幾時有話過要睇人嘅amylase

Yes
So D

但點睇有diffused light 呢個variable?

利申中文考ge
我寫都係寫HCO3-,寫唔好比CO2係低光度下已經成為 limited factor

diffused light你都係pot到個正比ge graph
個y=mx+c多個constant姐
但係CO2一有variation你個graph唔用得wor

但你一樣證明唔到light intensity is the only variable since the amount of diffused light is variable

唔知點解今次同上年一樣自我感覺良好但上年得lv 5

掂啦 你今年5**

Yes, very obvious

A B C都有意思
因為show only xxx can't give positive results

問點解plasmid 有d無gene of interest
問antibiotics medium function

Lm 等人答

其實最好cover with black curtain + bicarbonate
-> show the bulb light only variable
-> rate of photosynthesis enhanced to become more observable

A B C都係research methodology

If u say that use of black curtain is to prevent effect of diffused light but they are constant in every moment

所以前者,
Black curtain 先係回應緊題目

後者bicarbonate 係「已經」assumed bulb light is the only variable which we don't know

呢題寫左唔用light bulb 因為會有熱
