AOA

The O'level syllabus for Biology does not mention whether the individual stages of cell division (meiosis and mitosis) are required or not. Can someone tell whether I should study them or not?

No they aren't important, nor is there any question regarding them in the past papers...u just need to know the differences bw mitosis and meiosis which includes the pairing of homologous chromosomes etc.

Yes, transpiration pull only moves water up the plant but that water has dissolved mineral salts in it, which are carried up the xylem.

I think this covers most of everything you are likely to be questioned on. Solve a couple of past papers after reading through these notes, and you'll be good to go.

Are you talking about the storage granules in bacteria? As far as I know, those aren't a part of our syllabus.

Hi! So i have a question. Firstly is the voltage at the negative terminal of the battery 0? if so why? and i know it is there to create a potential difference so that current can flow but is there any logical explanation. Also, whatevr comes in the exam it's mentioned in our CIE syllabus right? like nothing comes which is not included in the keypoints of our syllabus?

 

[Saadarsalan]

Regarding redspot's keypoints, calssified, topical, yearly solved. I cant say anything. I suggest to leave them and rather refer to your teachers since those keypoints are incomplete and often answers are incorrect.
