Biological approach to understanding behaviour: แบบฝึกหัด

• a.Neuroplasticity
• b.Localization of function
• c.Synaptic pruning
• d.Genetic inheritance

• a.The correlation between brain volume and intelligence quotient (IQ).
• b.The speed at which an action potential travels down an axon.
• c.The probability that two people with shared genes will exhibit the same trait.
• d.The percentage of a population that carries a specific recessive gene.

• a.Participants with the long allele (l/l) were more likely to develop depression after experiencing stressful life events.
• b.The 5-HTT gene was found to have a protective effect against depression even when high environmental stress was present.
• c.Participants with the short allele (s/s) were more likely to develop depression only if they had also experienced multiple stressful life events.
• d.Stressful life events caused a mutation in the 5-HTT gene, leading to depressive symptoms regardless of the initial allele length.

• a.They are exclusively produced in the brain's prefrontal cortex to regulate mood.
• b.They act as specific DNA markers during the process of genetic replication.
• c.They cross the synaptic gap to transmit electrical signals between neurons.
• d.They travel through the bloodstream to affect target cells in various organs.

• a.Women preferred the scent of men with MHC genes different from their own.
• b.Men preferred the scent of women who were currently in their ovulatory phase.
• c.Women preferred the scent of men with MHC genes identical to their own.
• d.There was no correlation between MHC gene similarity and scent preference in humans.
