Answer:
A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."
D. The rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
Explanation:
It is important to consider that Kenny hikes all day but at a steady pace, whereas Janelle runs very fast. So Kenny's case, the supply of oxygen is sufficient to maintain aerobic respiration within the muscle cells. During this process only CO2, Water, and ATP are produced; therefore, there is no oxygen debt. We should keep in mind that the body shifts to anaerobic metabolism only when the supply of oxygen is limited.
In Janelle's case, running fast would need energy at higher rates and the supply of oxygen would not be sufficient to generate a high amount of ATPs. Therefore, to compensate for this deficiency, cells will start fermenting glucose to lactic acid and produce ATP and maintain energy demands. This lactic acid causes fatigue and this is why Janelle has aching and breathing hard. Breathing hard is also automatic reflux to inhale more oxygen and meet oxygen demands but even breathing hard would not be able to make it and the body will shift to anaerobic respiration automatically.
Answer:

Cornelius Agrippa (1486-1535) was a German mystic who practiced a "science" that combined alchemy, magic, mysticism, and astrology. Two of his books are Three Books of Occult Philosophy and On Calling Spirits. Through the writing of Agrippa, Frankenstein becomes very interested in alchemy, which is a pseudoscience whose main object is to find a way of turning base metals into gold. You could say that Frankenstein adapted the thinking of the alchemists and instead of transforming other metals into gold attempted to transform a corpse into a living being.
An interesting story about Agrippa concerns sightings of him after his death:
There were rumors that Agrippa had summoned demons on his death bed, and that a black dog roamed the countryside as his familiar. The black dog appears in tales as Faustus, Mephistopheles, and even as a grim in the Harry Potter series.
