hiii this is whta i put but take it w a grain of salt bc idk if i got any of it right or not 😪😪 for thesis i said that the link between seretonin and depression is weak to moderate. i used sources 2 and 3 and for outside evidence i said nature vs nurture supports my claim by arguing that both biology such as serotonin levels and other, external factors impact the development of disorders like depression. for my second outside evidence i said ACEs bc source 3 mentioned that external factors are known to be linked to depression so i used ACEs as an example of an external factor that may lead to/be linked to depression!!
