From the contour line that is a combination of two line segments that connect but do not intersect, 500 and 750 represent elevation on the topographic map. There are 5 contour lines in between the given elevations 500 and 750, therefore, the contour interval is 50. Since the peak of the mountain is 2 contour lines from 750, the elevation of the mountain is 850. Hence, the answer is 871 meters.
Answer:
B
Explanation:
The lung not being not been able to exchange and remove the carbon dioxide created a health problem due to the concentration of hydrogen ions (H+) being 10X being higher than in normal body. Although the difference is just about 1, it will result increase hydrogen ion concentration 10 times, similarly an increase or decrease in pH from 4 to 2 will give rise to 100 times increase in hydrogen ion concentration. It can equally be applied to hydroxyl in concentration.
