Deep water currents affect the number of organisms found in the area by circulating nutrients due to upwelling. Upwelling is a process where cold water surfaces and encourages nutrients to the surface. When exposed to sunlight, they initiate energy which keeps the flow of the ecosystem.
Explanation:
But researchers in Israel have done a study showing that families have characteristic facial expressions, ones even shared by blind members of the families. The results suggests that such expressions may be inherited and thus under some genetic control.
A control group is important to a controlled experiment because it is used in an experiment to establish its validity.
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.
