<span>The mantle is more dense, so it can not B.
Not even A , because the crust sure does contain naturally occurring radioactive material. Heat is also not efficiently transferred to the surface--most ground is cool,
so correct option is none is above that is D
hope it helps</span>
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.

Explanation:
What do the cell walls of plants and the extracellular matrix of animal cells have in common? They have functional connections with the cytoskeleton inside the cell.
Answer:
Epidermis
Explanation:
The epidermis is the thin outer layer of the skin.
Answer:
The incorporation of radiolabeled amino acids during protein synthesis occurs when the data shows the organelles involved with protein synthesis, packaging and transport, that is, radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles (option C).
Explanation:
Protein synthesis in the cell occurs when RNA -which contains the sequence of triplets or codons that make up the genetic code- is coupled to ribosomes.
Each codon or triplet, consisting of three nucleotides, will give instructions for specific amino acids to be incorporated into the polypeptide chain that is being synthesized in the rough endoplasmic reticulum.
The Golgi apparatus is responsible for packaging or packaging the newly synthesized proteins in secretory vesicles for transport.
<em>In consecuense, </em><u><em>radioactivity levels would increase in the organelles involved in protein synthesis, packaging and transport, the rough endoplasmic reticulum, Golgi apparatus and secretory vesicles</em></u><em>, respectively.</em>
