SPM BIO AMALI 2024 - RATE OF PHOTOSYNTHESIS

[@adzalanbinmohdaminkpm-guru8710]

thank you...much appreciated

[@shandypiemenghong]

Teacher, can i ask a question 😊
If 2 hydrilla sp is placed in sodium hydrogen carbonate , predict the total number of bubble released ? Explain your answer.

[@narcoleptic1887]

they'll fight tgt for the co2 more competition

[@tayshaawnmathew1071]

more total number of air bubbles released in 5 minutes . more hydrilla sp leads to higher rate of photosynthesis more oxygen gas released

[@fluffmochi]

Thank you teacher 😍

[@gundamplay7383]

Teacher, may I ask a question. Do hydrilla sp. need to underline below the hydrilla

[@sereneching3836]

yes

[@midzy_panda0419]

Yes all scientific name should be underlined in writing 😊

[@gundamplay7383]

@@sereneching3836 But my school teacher told me that no need to underline

[@v1en_a]

@gundamplay7383 underline better because it is a scientific name

[@rayjim9371]

Good question, I think just underline, can't be wrong by doing so

[@gwenhew9476]

老师你好，请问kimia amali已经出了没有prosedur的，bio amali 还有可能会出没有prosedur的吗？

[@Light-no1hp]

Prosedur is given

[@DeadLock07.]

@@Light-no1hpu sure? Ithink well probably get procedure as well but im not sure

[@imanub8692]

nah procedure is given but we might need to do graph

[@ccjy0707]

the number if air bubles released in 2 minutes and average shouldn't have 单位 right ?

[@charmainelo4696]

Teacher may I ask why does the number of air bubbles have a unit? (At the table)

[@Ilmuhisab]

Teacher, may i ask a question, how do i know from the table that 11 bubbles was released in 6 minutes?

[@nurinirdina1992]

i got confused here too, isnt supposed to be 21 bubbles in 6 minutes? cmiiw

[@郭城君]

mine 300 over

[@靖康-k4q]

teacher, I want to ask, we can't write value in out observation right? our bio teacher said that write value will deduct mark

[@iivyqr]

eh?? i thought observation must give exact value?

[@lovepeachies]

observation must give value

[@靖康-k4q]

@lovepeachies my teacher say they change the rules already, they don't accept values for observations anymore

[@lovepeachies]

@@靖康-k4q i think ur teacher is wrong

[@wwf7212]

Is relationship and hypothesis same?

[@sitisarah4750]

yes but the relationship is base on the question while the hypothesis is base on the experiment

[@wwf7212]

@sitisarah4750 alr tqsm

[@jordanhengzihoumoe5697]

8.22 is the data for rate of photosynthesis is correct?

[@Lee-g3w2k]

i don't think so, second one should be 21/6=3.5

[@Lee-g3w2k]

but if u look at bi), the total bubbles become 11 for the second one so🤷‍♂

[@junteo2719]

我考trial也是考这个，遇到的问题是看不到bubble😂

[@Johnleewallet]

所以我们必须一直等5分钟 after changing the sodium hydrogen carbonate?才开始算6分钟的时间, 总共必须等33分钟？
