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.
<u>Answer</u>:
<em>Annual precipitation and average temperature
</em>
<u>Explanation:</u>
Weather is referred as the temperature and precipitation recorded daily but climate is the <em>average temperature, precipitation, atmospheric pressure, wind and humidity recorded annually</em>.
Climate is also meant by the average weather of a place. The elements that are commonly found in <em>description of the climate is annual precipitation and average temperature of a place or region</em>.
Precipitation is defined as product obtained by the <em>condensation of the water vapour present in atmosphere</em> and which falls under the <em>action of gravity. </em>
Answer:
are most likely due to the fact that and are most likely due to the increased
Because the pressure of the rain is strong which affects the rain to become even stronger and forms a hurricane.
