Unit 7 Biology Sri Lankan A Level

The unit 7 is all about coordination and homeostasis.

I will  give you some definitions will will  be very useful in your exams:

coordination: when the conditions of the external or internal environment of an organism changes and a specific response is made by the organism, and the a=organism gets adapted ,thus maintaing constant internal conditions resulting in the survival of the organism

white matter: collection of axon of neurone
grey matter: collection of cell  bodies of neurones

Remember this way: u got a huge collection of rats with huge tails.The collection of the rats id the grey mater and the collection of the tail of rat is the white matter.
