Answer:
The limbic system.
Explanation:
The limbic system is the part of the brain involved in our behavioral and emotional responses, laughter for example, or aggression, as it is the case here. It controls some behaviors that are essential for survival: finding food, reproduction and self-preservation. It is a network of structures located beneath the cerebral cortex and above the brainstem. The two of the major structures of the limbic system are the hippocampus and the amygdala.
Answer: Internal influences may mean health hormones, as hormones are a key structure in how we function. An external influence could be sleep, as humans need sleep as a way to recharge, or diets as they have an effect on both hormones and physical durability
culture is the correct answer in my opinion.
