Answer: 0.69 m/ mile.
Explanation:
The altitude gradient between two cities X and Y = 
Given: Two cities are separated by 200 miles.
City X has an altitude of 122 meters.
City Y has an altitude of 260 meters.
The altitude gradient between two cities X and Y =
Hence, the altitude gradient between the two cites = 0.69 m/ mile.
Answer:
Option 3. cohesion transpiration is the correct answer.
Explanation:
Plants release water through transpiration while cohesion is responsible for moving more water throughout the xylem. When the water evaporate through the stomata, more water is pulled from roots into stem and eventually reach the leaf this process is called transpiration-cohesion theory.

Based on respiratory function tests, the correct options are:
- spirometer.
- vital capacity
- residual volume.
<h3>What is a respiratory function tests?</h3>
A respiratory function test is a test done to evaluate the ability of the lungs to take in air and remove carbon dioxide
The machine used for this test is called a spirometer.
Therefore;
- Ms. L's respiratory function was evaluate using a machine called a spirometer.
- The amount of air that can be expelled by maximum ex-halation after maximum inhalation is termed the vital capacity
- An increase in the amount of air remaining in her lungs after a normal expiration is called the residual volume.
