Explanation:
Like all psychoactive substances, amphetamines affect the central nervous system and have stimulating effects (empathy, sensuality, confusion, etc.), producing an alert state along with various reactions in perception. Some individuals also report optical and auditory illusions. On many occasions this is also favored by the existence of intense visual and auditory stimuli, as happens for example at parties. However, most of these desired effects have tolerance with repeated doses of the same substances and even cross tolerance with doses of other substances. With the appearance of this tolerance other effects appear such as aggressiveness, anxiety symptoms, panic attacks, etc.
Among the medical complications related to the use of these substances, acute neurological complications, seizures and cerebrovascular diseases stand out.

Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.
The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.
Answer:
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs called alveoli in mammals and reptiles, but atria in birds. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.
