According to Jeffrey Gray, a British neuropsychologist, the behavioral inhibition system (BIS) is activated by danger signals , resulting in the experience of anxiety. a. within the amygdala only b. arising from both the brain stem and the cortex c. descending from the cortex d. ascending from the brain stem

c. arising from both the brain stem and the cortex

Explanation:

The behavioral inhibition system(BIS) according to Jeffery Gray can be explained as neuropsychological system which gives the prediction of response from individual to signal of anxiety-relevant in a particular area or environment. He stressed that BIS have a relationship of sensitivity to punishment along with avoidance motivation. The The behavioral inhibition system is usually activated when individual is experiencing negative event/ stimuli, boring moments, or punishment. Then by the time the body respond to the cues of the negative stimuli involving punishment, then the (BIS) brings avoidance of the negative event. When there is activity of( BIS) then there will be heightened sensitivity to punishment as well as nonreward experience.

It should be noted that the behavioral inhibition system (BIS) is activated by danger signals arising from both the brain stem and the cortex resulting in the experience of anxiety.

it's c. (to reduce the greenhouse effect/carbon gasses)

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
