Fever c) is regulated by chemicals that reset the body's thermostat to a higher setting

Explanation:

Fever is a high body temperature and is one of the ways our immune system attempts to combat an infection. It is also referred to as pyrexia and it could be more than between 37.2 and 38.3 °C (99.0 and 100.9 °F) in humans, there is not a single agreed-upon upper limit. Temperature is regulated in the hypothalamus. Fever helps your immune system fight infections by speeding up the functioning of cells and it makes it harder for bacteria and viruses to thrive in the body.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
