Apersons amygdala is damaged, and he tends to get angry less than he used to. this suggests that the amygdala?

is involved in regulating emotions

Explanation:

The amygdala is part of the limbic system. The amygdala is thought to play an important role in decision making, memory and emotional processing. These emotions include fear, anxiety and aggression which can be linked with anger.

In fact, animal studies have shown that animals with a damaged amygdala are less aggressive.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.

it is called kinetic energy
