我咁睇啦
Logically

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

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

唔係suggest one modification咩

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

但佢題目show how light intensity is the only variable

咁你答左咩？
你答案未見過

卷已up
求答案

Q3佢問at the beginning

Factors affecting photosynthesis有
Light intensity
Co2 conc
Temperature
我答左第三個

E4問乜

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

易到咁

你尾機jeh

No la, recombinant DNA technology is much easier than PCR la
仲要淨係考digestion同selection

信你 因為5**
總之唔係bicarbonate

未必 co2 conc都係其一

Yes

我有諗過light bulb但我諗唔到replacement LOL

Q3 我都睇錯係ending
咁係Benedict negative, iodine positive, protein positive

唔係suggest one modification咩

我唔知了
我覺得佢咁問，前提覺得light is not only variable
-> show how light is the only variable

咁係Benedict negative, iodine positive, protein positive

Agger

Q3 我都睇錯係ending
咁係Benedict negative, iodine positive, protein positive

9. DNA coding strand唔係同 mRNA一樣咩

Why use identical twins ?
Because they have identical genetic makeup to increase accuracy?

Q3 我都睇錯係ending

9. DNA coding strand唔係同 mRNA一樣咩

Coding <> template
Template <> mRNA
mRNA <> tRNA

寫左擺a beaker of water in front of the beaker of solution

Coding <> template
Template <> mRNA
mRNA <> tRNA

answer is A?

原全唔知幾時embryo implants

Yes

係
Coding = non template = complementary to template strand
