I only watch some tbh on annoying concepts, to see how he explains it
Yeh i know what u mean. tbh I watched his videos on MAB. It would have bean 10 times better if he had used some animations instead of writing everything down

teacher read out my answer

gg lol
Haha i got 7/8 for that ;) hahaha, it was a hard question though, spent like 45minutes on that, had to write 2 extra pages but it was a 8 marker so I was thinking of what other info could be relevant and yay that i covered it all. I didn't cover the dot point about how vaccines are implemented worldwide though (mass programs, technologies etc.)

Hey guys, can someone explain the larynx to me?
Sound box consist of vocal cords, air passes through causing them to vibrate = sound. Cords can be adjusted accordingly* (PUN) for different pitches.

Would anyone be able to give me a model of a feedback mechanism for Maintaining a Balance 1.11 please? I have no idea why I don't have one in my notes and I can't find one

accuracy reliability validity.png

Also not sure if this would help anyone but this is a summary of what to talk about for accuracy, reliability and validity in both first hand and secondary source investigations.

I always get mixed up and forget, maybe I'm just stupid but it's a good summary for me

Model of a feedack
Stimulus -------> Receptors -------> Control Centre ------> Effector --------> Response
Easy pneumonic to remember (Some Ranger Make Caucasians Eat Rice)

Increase in temp ----> Thermoreceptors in the skin pick up this change -----> Relays the message to the Hypothalamus ------> Vasodilation, sweating, heat radiation from skin --------> Decrease in Temp

Before every exam, I always wonder how I get to this point of learning the content intensely one or two days before the exam, but I don't care enough that I keep doing it for the subsequent exam. :(
