Donna is concerned about her adolescent daughter's tendency to flare up at the mildest provocations. Donna says that her daughter refuses to see reason sometimes and seems unable to exercise much self-control. As a specialist in the development of adolescents, you would tell Donna that her daughter's behavior could partly be explained by the biological reason that: 1. by the end of adolescence, individuals have fewer, less selective, less effective neuronal connections than they did as children.2. the prefrontal cortex—involved in reasoning and self-control—has developed fully by early adolescence.3. the amygdala—the seat of emotions such as anger—matures earlier than the prefrontal cortex in adolescents.4. the corpus callosum, where fibers connect the brain's left and right hemispheres, thickens in adolescence.5. the amygdala—the seat of emotions such as anger

The amygdala—the seat of emotions such as anger—matures earlier than the prefrontal cortex in adolescents.

Explanation:

The amygdala is an almond-shaped neurons situated in the deep of the brain's central temporal lobe. It is responsible for controlling our emotions, memory, and also instincts of survival.

The emotions that are controlled by the amygdala are fear, anger, love, etc. This part of the brain helps to respond to the things in the environment, especially to those that arouse emotions in us.

In the given case, Donna's daughter's reasons for flaring up in the mildest way is because of the amygdala, that arouse the emotions of anger in her.

So, the correct answer is the third option.
