The autonomic nervous system consists of sympathetic and parasympathetic nervous system. The sympathetic nervous system controls the dilation of pupil whereas the parasympathetic nervous system controls the contraction of pupil.
A dilation response generally involves the widening of the pupil that may be caused by the adrenaline and drugs like cocaine, MDMA, amphetamines, hallucinogens and dissociatives.
Answer:
Explanation:
Before you begin the conversion process, you have to know that π radians = 180°, which is equivalent to going halfway around a circle. This is important because you'll be using 180/π as a conversion metric. This is because 1 radians is equal to 180/π degrees. It's that simple. Let's say you're working with π/12 radians. Then, you've got to multiply it by 180/π and simplify when necessary. Here's how you do it:
π/12 x 180/π =
180π/12π ÷ 12π/12π =
15°
π/12 radians = 15°
