Question is pretty much in title. :smile:

Also, state in the thread how you found the paper. :yes:

Personal:

Good/normal paper - apart from annoying and stupid wolf question lol.

CO2 Essay :woo:

Introduction - effects of CO2, animals, plants, microorganisms.

* Photosynthesis - fixes CO2, produces glucose and other organic malarkey: LIR, enzyme-controlled, described process and stated equation.

* Respiration - uses organic malarkey and produces CO2.

* Haemoglobin - Bohr effect, CO2 causes Hb to change shape, releases O2 in respiring tissue, curve shifts to right.

* Chemoreceptors - detect changes in CO2: process, balance, form of negative feedback.

* Global warming - fossil fuels, deforestation: both human impact - affect abiotic and biotic e.g. habitats and extinction of organisms.

* Gas exchange - Lungs in animals + adaptions, stomata in plants + adaptions, microorganisms use CO2 for respiration to decompose.

Summary - summing it all up, innit. :gangster:

Share your thoughts and feelings on the paper - most specifically the essay since there's already another thread for "answer discussion".

Thanks. :smile:

Good paper.
Disease essay.
What I wrote about:

•

Genetic diseases - Diabetes, Cystic Fibrosis, Dominant/Recessive alleles

•

Lifestyle - Cancer, Tendonitis, Coronary Heart Disease, Emphysema

•

Pathogens - How they spread (Droplets, STD, Cuts/Wounds, bites (dog/mosquito), etc.), how they affect the body (e.g. viruses invade cells, bacteria release toxins), examples (MRSA, Cholera, Athlete's Foot).

Disease
-cystic fibrosis
-cancer
-heart disease
-lung disease
-cholera
-(Irrelevant point i know but, hyperthermia)

Had lots of time for it though :smile:

It contributes to Typhoid.

Good luck. :smile:

CO2
Carbon cycle
Photosynthesis
Respiration
Greenhouse effect/global warming & effects bla bla bla
Acid rain - not really relevant but thought I'd include something off syllabus
How CO2 increases blood pH, detected by chemoreceptors, decreases heart rate etc. etc.

I wrote 2 and a half pages, which although probably seems small for most people was really good for me cos I'm AWFUL at essays!
Was pleased with the titles tho - but would still have preferred 'Cycles in Biology' or something on proteins.

Wrote basically the same :smile:

aint we sexy...

diseases - focuses on splitting it into environmental and genetic causes

1. viruses (very gcse, was rubbish :frown:

)
2. bacteria (again, my explaination was v basic)
3. CHD and other heart diseases stuffs, atheroma etc, risk factors
4. lung disease. big mistake. mixed up emphsema and fibrosis...
5. cancer. awesomeage! how mutations cause it, envorinmental factors like mutagenic agents, genetics, oestrogen dependant breast tumours...
6. Genetic diseases. quite brief... genetic corss diagrams to show how it can be carried and inherited

any predictions on what ill get? :P

Basiacally the same as the OP but I forgot all about the bohr effect and I talked a bit about the carbon cycle and food chains.

The cause of disease one: said basically caused by pathogens:
talked about bacterial conjucation against antibiotics, mrsa, cholera, bacterial resistance and for viruses, the cold and hiv.
Genetics: recessive dominant alleles, cystic fibrosis
Lifestyle, emphesyma, obesity leading to heart disease.
Then talked about how lifestyle and genetics linked: cancer, mutagenic agents increase changes, protocongene mutations. diabetics, caused by genetics of lifestyle in case two and put an example of recent research from new scientist and polycystic ovary syndrome how caused by genetics (probably) but can be contolled by lifestyle.
Then summarised by giving quick overview of treatments, stem cells etc

Oh cool I did exactly the same as you except for Tendonitis.

Cool. I only did tendonitis because I have it, so obviously it was fresh in my mind and I had a vague idea about it.

Fossil Fuels / Deforestation ---> CO2 ---> Global warming ---> Melt ice craps ---> Sea levels rise ---> Habitats destroyed ---> Animals e.g. polar bears endangered / extinct.

Seriously? Was that on your exam?

It's positively indoctrination if it was; environmental nonsense is on literally every subject's syllabus, except maths :love:
