Okay so after history not goin as well as id planned i really need to do well in ag to make up the points. Iv done a good project so if i pass the paper il get a C2 or C3 but would love a B iv got a week off before its on so iv some serious cramming to do has anyone got any tips on what i should focus on or predictions for what will come up or can you even predict for ag???any help please????
Bit early for me to be thinking about Ag, I have Biology and Chem to take care of first
get all the answers from examination.ie and go over all the years.... that really helped me..
Go over soil, genetics, grass, animal figures ( birthweight, gestation lenght..), phylums...flushing and steaming up in sheep production.
Can someone tell me what soil flocculation is? I never really covered it.
Pfft, it's some peoples next exam. It's not all 'bout you y'know
In fairness, I did say "for me" (indicating that I'd be checking in with this thread later).
Thank you!!!according to my rapid revision flocculation is when ''clay particles come together into floccules or small clusters to improve soil structure''.Dont know how much use that is to you, dont really understand it myself either!!
Haha I think I have the same one! I'm kinda in an Ag mood so I'll talk about what I know...Might get your brain going!
Functions of a leaf.... Food storage, gaseous exchange, photosyn, transpiration.
Conditions for germination-- Water , oxygen , warmth..
Seed structure --- Testa, Embryo, Endosperm.
Stages of nutrition-- Ingestion, digestion, absorbtion, assimilation, egestion.
Oxytocin- Milk let down , Prolactin - Milk production.
Zoonoses -An animal disease that humans can contract.
Milk is 87.5% water.
Wire worms - Arthropoda, Lung worms - Nematoda, Earthworms - Annelida.
Apples- Rosacaea .. Docks - polygonacaea..
Make sure you have a general knowledge of everything. They always throw in a stinker of a question or two, sometimes not even on the syllabus. I also wouldn't leave out any section. Study every topic, even if you only have the most basic knowledge of some of them. Anything could come up in the short questions, and sometimes you'll get 2 topics within one of the later questions
Jeeeeeesus, you're really testing me here. Errr, I think it's something to do with ions and cations, and the soil particles forming lumps (crumbs) Sorry, I've drank all my Ag. Science knowledge away *shivers* It'll be in the experiments section, anyway. Surely you have a revision book? I like how rainbowtrout thanked the post, and didn't answer you No more free answers on here anymore, you've to buy the book
I thanked it because it was good advice
It's where small soil particles (clay and silt) cluster together to form larger particles or structures called floccules. They are normally attracted to each other due to their cations and the polarisation of water in the soil.
They then trap larger particles which have no ions such as sand to form even larger particles.
If you could imagine a chain of silt and clay particles attracted to each other, forming a ring around a sand particle holding it in place, that's a floccule.
If i leave out grassland and soil will i still be able to pass??? il still have the biology,crops,animals,genetics and phylum covered i just really dont have time to do grassland and soil too??????
I wouldnt leave anything else to be honest :
Question 7 (my favourite )
Gametes, Alleles, Haploid, Diploid, Heterozygous, homozygous, incomplete dominance, sex linkage, multiple alleles, mutation, Dominant, recessive, inbreeding, crossbreeding... Anything else you can think of !
B. your crosses
C. Applied Genetics
*Performance ant progeny testing
A. Factors affecting soil formation
Usually you have the choice. Podzol is the easiest !
C.Soil Forming process
Adv. + Disadv. of liming
E. Properties of Soil
Physical properties (i.e. texture, water, structure etc..)
Chemical properties (I.e. Cation exchange capacity..)
Biological properties (i.e. earthworms .. )
Any else you can think of !
For question 4 simply study your experiment copy.. an experiment takes about 15 mn to learn it's really no big deal
These are not predictions but I just would not take the chance to leave out anything..
Sure you'll pass, but I'd recommend grassland..One of the easier parts of the course I think!
I tend to opt for these two questions also. Q.2 is ALWAYS on soil, Q.7 ALWAYS genetics, Q.4 is the experiments and Q.9 is the scientific explainations, Q.1 is the mixed bag of questions and then i'm left to choose one nice one from whatever is left. I find it the easiest way to do the exam. I'm hoping the experiment questions are nice, theres just so many to learn.
My teacher posted me out some extra notes last week on organic farming and a note to say she thinks there may be a question thrown in somewhere about it.
Eg. Differences between fertilizers spread on a field with normal potatoes and one that is organic.
Something along those lines. I wouldnt go into too much detail on it though.
Have to say the AG Pre's this year were way to easy and I seem to have done less study since.
