The answer is commensalism. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism is when both partners benefit. Commensalism is when only one species benefits while the other is neither helped nor harmed. Lastly, Parasitism is when one organism (the parasite) gains, while the other (the host) suffers.
<span>The independent variable is the variable that does not change despite inputs. In this experiment, the independent variable is the color of mashed potatoes. The control group is what the experimental group is measured against to determine how much change there is. Plain potatoes is the control group. Number of samples is how many different opinions are taken into account. In this instance, the number of samples is equal to the number of students, or 100. There are no repeated trials. She only did the experiment one time.
The hypothesis is what the experimenter believes will happen. Gloria did not state the hypothesis for the experiment. She could have said, "I believe that students will choose colored mash potatoes than plain."
This experiment can be improved by repeating the experiment at more schools. Also, it can be improved by increasing the number of students tested.</span>

angle of incoming sunlight
Explanation:
The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight.
- Climate is simply an extended study of weather over a long period of time.
- The elements of weather like temperature, pressure, rainfall all conditions climate.
- The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth.
- Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon.
- The polar and temperate regions receive diffused sunlight because the sun is at an angle there.

Answer:
sympathetic nervous system
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls the involuntary body functions as heart rate, breath rate, perspiration etc. The sympathetic nervous system is specifically responsible for the increase in the function of body functions when the body perceives a threat. When faced with a threat or distress, the sympathetic nervous system initiates physiological reactions known as the “fight or flight” response, thereby increasing the body’s alertness to such threat. Examples of increased body functions or “fight or flight response” include increased perspiration and increased heart rate, as exhibited by Blair.
