Based on the table "Fatty acid composition of some common edible fats and oils" from http://www.scientificpsychic.com/fitness/fattyacids1.html, 85% of the total fatty acid residues of olive oil are fatty acids containing 18 carbons in their structure.
These fatty acids are stearic acid (3%), which is saturated, oleic acid (71%), which is monounsaturated, and linoleic and alpha-linoleic acid (10% and 1%, respectively), which are polyunsaturated.
Answer:
Independent variable: DIFFERENT TEMPERATURE
Explanation:
The independent variable of an experiment is the variable that the experimenter changes or manipulates in order to effect an outcome or response in the measured variable/dependent variable.
In this experiment, a scientist wants to determine how temperature affects photosynthesis. He sets up the experiment by adding 20ml of water at different temperatures to three test tubes. Hence, the independent or experimental variable is the DIFFERENT TEMPERATURES GIVEN TO EACH PLANTS IN THE TEST TUBE because it is what the experimenter changes in order to effect a measurable outcome i.e. oxygen released in each balloon as a result of photosynthesis, which is the dependent variable
It is known as the Magnetic Field.
