a) From this, where does it seem most likely to have come from?
b) By what means could it travel?
c) How would you compare the rate of invasion between 2003-2006?

9. How can biodiversity be reduced by introducing more species into a habitat/area/ecosystem?

10. Without a license, animals and plants may not be taken from one country to another and so it is regulated. What sort of species can be carried without anyone being aware of it, and in what form?
11. In what ways can invasive species cause £12 billoin worth of damage?

12.

a) What is Biological control of species?
b) Give two examples of a species controlled by their natural predators.

Has anyone got the actuall pre-release... because ive lost mine? :/ if you could scan it or PDF of something... i would love you forever

Can anybody answer these 2 questions, any help will be appreciated!

1.) Describe the role of the physiotherapist in treatment of skeletal-muscular injury.

2.) Describe a set of exercises to treat one such injury.

Thanks

I was looking through the specification and there was a bit I didn't understand:
There is often more than one way to achieve an agreed target (enhanced fitness, cure, recovery, rehabilitation)
I don't get why this is the case. Can someone please help me out?

Enhanced fitness - improve the fitness of a client eg to someone this might mean improving their flexibility and to somebody else it could mean being able to run faster. It means different thibgs to different people.
Cure - Repair of damaged tissue eg a sprained ligament or mending a broken bone
Rehabilitation/Recovery - Bring the patient back to the same level of fitness or function after an injury or illness. For example a training programme that progressively builds up their strength and flexibility.
Did that help?

I think the physics one went so well omG it was better than the chemistry one by far but I think Biology will be the toughest one yet. I just remember coming out of the exam so pleased :') but will be a kick in da butt if I actually did bad when I thought it went well

And do you think that we need to concentrate on Circulatory system and the bones and stuff.

We havent been asked much on it in past examz. so do you guys think that we should learn it?

I reckon just learn it anyway, there's no harm

I skiped bones bit xD

Yeahhh thats boring
I think the thing to do with Parasitism and symbiosis will come up though, so maybe revise that??

Thanks, and I know lol. Are you only using the CGP revision guide?

I'm using the Letts and Lonsdale Biology Essentials. It has everything you need to know in bullet points and i just memorise that but if Ifeel like it doesn't go into too much detail which I would need for the exam, I refer to the CGP book for example about fitness and treatment

I also do past papers

Let me test you?
