Aerobic and Anaerobic Cellular Respiration

The correct answer is - aerobic cellular respiration, oxygen, anaerobic cellular respiration, energy, lactic acid and muscle fatigue.

Explanation:

The most common type of cellular respiration is aerobic cellular respiration which takes place in the condition where enough amount of oxygen is available that provides energy to the body.

In absence of enough amount of oxygen the anaerobic cellular respiration, when an individual exercise intensely his body not able to provide enough amount of oxygen to the cells so, therefore, perform anaerobic respiration to produce energy however this cause muscle fatigue due to a byproduct known as lactic acid.

explanation:

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.
