They will either reduce the amount of re-absorption or block the enzyme that is trying to break down neurotransmitters

Biological Level of Analysis Learning Outcomes 1. Outline the principles that define the biological level of analysis. a. Patterns of behavior can be inherited: There is innate behavior “hard-wired” in organisms that is carried on through genetics. It makes certain stimuli generate certain response and is usually evolutionary. b.
