Previous research shows that some human populations living at extremely high altitudes have larger lungs. Research also shows that at high elevations the oxygen concentration in the air is lower, and people in these areas are at risk of not getting enough oxygen. Required:
a. Generate a hypothesis about why people in high altitudes have larger lungs.
b. Describe the type or types of data you would ideally collect to test this hypothesis.
c. Describe what hypothetical data might support the hypothesis.

People in high altitudes have larger lungs as compared to lower altitudes.

Explanation:

Those people who lives at high altitudes have larger lungs in order to reduce the excessive ventilation of the lungs. There is shortage of oxygen at high altitudes because oxygen is a heavier gas so for storing more oxygen in the lungs the volume of lungs increases. Those people who lives at high altitudes have higher capacity of lungs as compared to people who lives at low altitude. To test this hypothesis we have to collect the data of two types of people such as people who lives at high altitude and people who lives at lower altitude. If the data shows larger lungs of people who lives at high altitude so our hypothesis is correct.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
