How you are not verified and the amoeba sisters are? I do not know. You cut to the chase. State the facts, and it's much easier to not zone out when you're talking and you don't fill your videos with cartoons and drift off to other topics, as you say yourself "no waffle"

I just wanted to thank you for all your help. I now enjoy biology and find it fascinating. The day before my paper 2 biology mock I watched all your videos regarding paper 2 bio and achieved a grade 9. Compared to my grade 5 in the paper 1 mock when I didn't use your videos. Now I will be taking biology for a-level and you have heavily influenced that decision so thanks again.

[@hanidhchohan]

people NEED to realise that this guy can easily boost your grade to a 9. No matter how many views he gets he will always be underrated

[@rehya5088]

The defination of Homeostasis varies throughout various GCSEs resources.
Another definition of Homeostasis is = maintenance of constant internal environment in the body.
Would you still get the mark if you wrote the above definition or should I remember 1:09 definition instead?
Thx

[@DaringToast]

It's a good definition to remember in your head, but in an exam it's better to write down his definition, the green highlights show potential mark points, so you should make sure to never emit the highlighted bits when in an exam

Is the coordination centre the same as the CNS?

[@Freesciencelessons]

That's correct in the case of the nervous system. In the case of hormonal systems, it can be a bit more complicated (eg the pancreas is the coordination centre for the control of blood glucose).
