Explain physiologically what happens normally with this G-coupled Protein process (molecule binding to a G-coupled protein receptor) Explain the physiological reason caffeine is making Phoebe more awake.

Antоn аnd his friends аre discussing а study he read abоut in his develоpmental psychology class. In the study, the researcher made the claim that most middle school students who are bullied have low self-esteem. Clarissa questions the study, saying, “I am not sure that I am convinced. I am not sure you can really measure being bullied.” Quinn also questions the study, saying, “Which middle school students did they study? I am curious if they included both private and public school students.” Manish is also curious about the study, asking, “I wonder how strong the relationship is between bullying and self-esteem. Could you predict one from the other?” Why should Anton NOT interrogate the internal validity of the study?
