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:
meiosis, hope this helped!
Explanation:
Answer and explanation
1. Cloning differs from budding as it generates a genetically identical COPY of a cell or organism while budding produces a genetically identical offspring.
2. Firstly it can take place quickly, allowing the pioneer species to establish themselves in their new habitat, out competing slowly -reproducing species.
Secondly since all the offspring are genetically alike, it ensures that if the parents are successful in their habitat, the offspring will also be successful, provided environmental conditions do not change .
3. Plant cloning uses one of the plant organs can be roots , stem and etc ..while animal cloning only uses a single cell
The answer is: " invasive " .
