原全唔知幾時embryo implants

3
因為stage 4 is > 100cells
-> already differentiated

If 3 is already implanted

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
:^(

Coding strand 係aac template strand咪係ttg mrna咪係aac trna咪係uug

巴麻美學姐 2017-4-24 15:03:24 麻煩咁多位手足quote圖轉返做link先

係
Coding = non template = complementary to template strand

上面我見你答C

If 3 is already implanted

Becoz implantation is blastocyst
-> ball of undifferentiated cells after mitotic cell division of the fertilised egg

屌
睇中文版唔知原來編碼股就係coding strand

If 3 is already implanted

原來已經有cell differentiation

因為呢個out c
3 : blastocyst
After 3: blastocyst becomes embryo
-> have differentiated cells but the cells are not mature

其實我都覺得你bio幾勁
祝大家好運

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
:^(

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

信你因為5**
總之唔係bicarbonate

未必 co2 conc都係其一

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

或者咁講 modification要你eliminate以上除light intensity外既factor

但light intensity variable 本身唔係已經要eliminate 呢個factor from diffused light ?

大過一百就differentiated?

因為呢個out c
3 : blastocyst
After 3: blastocyst becomes embryo
-> have differentiated cells but the cells are not mature

D先係blastocyst
只有blastocyst 先會implant 入子宮壁

Blastocyst應該係partly differentiated ga ma?

因為每次cell division
1->2
size 會理論減少

所以不斷有水入番粒cell做cell enlargement, restored shape
