Physics, Chemistry and Biology: Post your doubts here!

[Mr.Physics]

Yes I do. I mean have this learner guide for biology that's really useful if you want but I just don't know how to send it to you here :c...
If you know how tell me so that I can send it to you!!

What is variation and natural selection ??

What is natural selection?
Natural selection is a process by which an organism that is well adapted to its environment has a higher chance of breeding and passing on its genetic information, than those who are less adapted.
What is variation?
Variation occurs as a result of mutations that create new forms of genes, known as alleles, which can be inherited by the next generation.

Can any one of you be kind enough and list out the important/most frequently asked half ionic equations?
TBH, I am not that good with half ionic equations, even though I know how to work them out, I still am planning to memorize the common ones to save myself some time
For ex: Half ionic equation for Oxygen in electrolysis is commonly asked:
.. any more like these? (2O2 → O2 + 4e-)
Thanks in advance

Well first of all ur ionic equation is wrong...
Its: 4OH- 》O2 + 2H2O + 4e-
Learn all half equations of the common electrolysis given in the syllabus (CuSo4, NaCl, PbBr etc...)
Other than that the ionic equations of precipitation and displacement reactions which im sure u'll find in ur chem!

NO TIPS FOR PHYSICS AND CHEMISTRY P3?

PEOPLE I have some guess questions for biology paper 3 tomorrow that I had just recieved !!
So I thought I would share it so that everyone can somehow benefit :').

CONCENTRATE ON THE FOLLOWING TOPICS :

-Classification_Keys.
*ARTHROPODS.

-Kidney Dialysis!

- Kidney Excretion.

-HIV and AIDS are veryy important!!

-DNA ----> Function/Location.

- Treatment of sewage is ALSO very important.
**Importance of microorganisms- chlorine**

-Structures of Viruses / Bacteria.
***Label them***

-Pesticides in food chain !!!
This one is really Important.

Well They all are the hardest Topics In biology
Well Fingers Crossed and Best of luck guys
