Hi!
Dr Pimler is going to have to run trials and experiments on this drug by successfully following the scientific method, and avoiding bias at all cost.
He will have to use certain things such as a placebo in order to avoid all forms of bias. He should also limit his knowledge of the own experiment, as to prevent observation bias.
Hopefully, this helps! =)
A hypothesis is a prediction drawn from a theory.
The answer is <span>. propranolol; norepinephrine
Propranolol is a beta blocker that will influence the receiver's blood criculation by affecting the operations in veins and arteries.
Norepinephrine, on the other hand, is functioned in order to regulate the hormonal and neurotransmitter function in our body.</span>
