Pls can someone explain nitrification?
So basically there is decomposition (of urine) so there is ammonium.
Nitrification is when the ammonium is turned into nitrites then nitrates.

Tomorrow's Biology paper ... anything to be clear about or any thoughts !?
PP2 topics-
1. pH effect enzymes
2. Turgid and flaccid plant cells
3. Balanced diet and how do energy requirements vary in different people
4. Measuring energy content in food
5. Structure and function of the phloem
6. Experiments investigating respiration – looking at CO2 and heat given off
7. Net exchange of gases in plants and experiments to show this
8. How platelets clot the blood
9. Vaccination
10. The iris reflex and how the eye focusses light on near and far objects
11. The skin
12. Germination of seeds
13. Codominance in genetics
14. Factors that increase mutations
15. The water cycle and the nitrogen cycle
16. Sewage in water systems
17. Yogurt production
18. Fermenters
19. The term transgenic
20. Advantages and disadvantages of cloning I'll also credit the youtube channel i got this from:

factors tht increase mutations : mutagens such as ionising radiation- UV, gamma
transgenic : when an organism contain a gene from another organis usually to produce a particular protein
adv and disadv of cloning -
adv- produce gentically identical offspring .
no varairion.
can produce anytime of the year and is fast
more offspring

disadv- no varaiation and so doesnt lead to evolution.
