- Problem 5 114. Biology With each breath, a person at rest breathes in about 0.50 L of air, 20.9% of which is 02, and exhales the same volume of air containing 16.3% O₂. In the lungs, oxygen diffuses into the blood, and is then transported throughout the body. Severe illness (altitude sickness) and even death can result if the amount of oxygen is too low. At sea level, atmospheric pressure is 1.00 atm, but at 3048 m (10,000 ft) it is reduced to 0.695 atm; the percentage of oxygen remains the same in both cases. Suppose that the temperature is 20 °C at both altitudes. What is the net number of oxygen molecules in each complete breath (a) at sea level and (b) at an altitude of 3048 m? (c) Use the results above to explain why peo- ple feel "out of breath" and must breathe more rapidly and deeply at high altitudes.arrow_forwardSolve question 35 and 36arrow_forwardFind a general solution of each of the following equations:8,9,10,11arrow_forward
- Questions 23 and 24 pertain to the following situation. From 2004 to 2013, the average salary, y, in thousands of dollars, for public school teachers for the year t can be modeled by the equation y = 33.374 + 9.162 In t, where t is the number of years since 2000 (i.e, t=4 represents 2004 and so on). 23. According to the model, what was the average salary for public school teachers in 2017? 24.
