Is it trump/obama/biden??!
Answer: I believe it would be letter (b)
Explanation: I had to answer this question yesterday and I am pretty sure this is the answer. Because it asks ¨the narrator gives an example of why oxygen is vital to climbers on Mt. Everest. How does the narrator develop this concept in the rest of the narrative?¨ so this is really the only plausible answer regarding the question.
Answer:
The viability of the TMJ disc cell decreased significantly (P <0.0001) without glucose. With glucose present, the decrease in oxygen levels significantly increased viability (P <0.0001), while a decrease in glucose concentration significantly decreased viability (P <0.0001). With glucose present, decreased oxygen levels significantly reduced ATP production (P <0.0001) and matrix synthesis (P <0.0001). A decrease in glucose concentration significantly decreased collagen synthesis (P <0.0001). The interaction between glucose and oxygen was significant with respect to cell viability (P <0.0001), ATP production (P = 0.00015) and the synthesis of collagen (P = 0.0002) and proteoglycans (P <0.0001).
Although both glucose and oxygen are important, glucose is the limiting nutrient for the survival of the TMJ disc cells. At low oxygen levels, the production of ATP, collagen and proteoglycan is severely inhibited. These results suggest that there may be more pronounced nutrient gradients in the TMJ disc and it may be vulnerable to pathological events that impede the supply of nutrients.
Henry spoke for over an hour. c
The term lost generations is used to describe writers and artists that coming of age happen during world war I.
These artists and writers forced to emigrate to Europe and work there. They often gathered to critic each other's work
hope this helps
