Drugs produce psychological effects by chemical actions on neurons.
Drugs produce psychological effects by chemical actions on neurons. What implications does this mechanism have for the traditional distinction between mind and body?
The purpose of aseptic technique is to control the conditions of the work environment
The purpose of aseptic technique is to control the conditions of the work environment so that sterile media remain that way until inoculated deliberately by the lab worker (you). The two tubes represent the "before" and “after" results when this is accomplished — a sterile medium is inoculated and grows to produce a pure culture […]

Extrachromosomal DNA is critical to the antibiotic resistance found in microorganisms, how do these DNA elements account for this phenomenon?
Explain the differences between an ion pump and a channel protein
Explain the differences between an ion pump and a channel protein (e.g. aquaporin). Specifically, what are their functions and what type of transport do they use? Answers longer than four sentences will automatically only receive half credit.
The primary mechanism of action of organophosphate pesticides is the inhibition of carboxyl ester hydrolases
The primary mechanism of action of organophosphate pesticides is the inhibition of carboxyl ester hydrolases, particularly acetylcholinesterase (AChE). AChE is an enzyme that degrades the neurotransmitter acetylcholine (ACh) into choline and acetic acid.
