1)	Because hormones travel through the blood, they can easily affect any tissue anywhere in the body.
2)	Hormones can only travel short distances between neurons.
3)	If a hormone is present in a high enough concentration in the blood stream, it will definitely affect behavior.
4)	Each type of hormone can only affect cells that have specific receptors.

Ketones and aldehydes react with sodium acetylide (the sodium salt of acetylene) to give alcoh R₁ OH R₁ C. R2 1. HCEC: Na 2. H30* -R2 Draw the structure of the major reaction product when the following compound reacts with sodi preferentially from the Si face of the carbonyl group. HC D=0C • Use the wedge hash bond tools to indicate stereochemistry where it exists. . You do not have to explicitly draw H atoms. • If a group is achiral, do not use wedged or hashed bonds on it.
