does anyone know the answer on how the brain controls temperature of the body

Haha You were right! The Nitrogen cycle was a six marker! You must have aced that then?

the hypothalamus in the brain controls thermoregulation because it has receptors that are sensitive to the temperature of the blood flowing through it

Yeah thats what i said, it also has receptors on the skin which transfers nerve impulses to the brain and CNS where the brain can control the temperature by homeostasis via negative feedback

what did people put for the healthy man/untreated type 2 diabetic question?? x

i wrote how type 2 diabetes means that the persons body is naturally resistant to insulin so therefore glycogen levels would decrease as insulin would not be able to convert the glucose into glycogen
So, glucose levels increase but glycogen levels are lower

Yeah thats what i said, it also has receptors on the skin which transfers nerve impulses to the brain and CNS where the brain can control the temperature by homeostasis via negative feedback

ahh phew yeah thats pretty much what i put- thanks!

I put roots instead of shoots when talking about auxin - like, "the root tip", etc. Will I lose marks for this?! I'm a complete idiot :/

i only mentioned hypothalamus and how it can detect it how much marks?

Don'

t worry I triple checked BTW you seem good at this prediction stuff what do u think is going to come up on C1 paper
