Answer:
C. experimental
Explanation:
Experimental variables are the variables that are changed during the experiments to observe the effects of these changes. An experiment usually has one or more experimental variables. An experimental variable that is changed to know its impact on some other variable is called the independent variable.
In the given experiment, goldfishes were exposed to various temperature conditions to observe the effect of temperature on respiration. Therefore, both temperature and respiration rate are the experimental variables here.
When it comes to freshwater wetlands, hydrology plays a large role in
nutrient stoichiometry and sensitivity to nutrient inputs. Although
wetland biogeochemists intuitively understand these important
relationships between landscape position, hydrology, and sensitivity to
nutrient inputs, these relationships have never been quantified using
geospatial data. The objective of this project will be to evaluate and
quantify the linkages between watershed catchment characteristics and
freshwater wetland nutrient sensitivity ur welcome
The answer is: decreased circulation
Increased flexibility tend to be achieved by implementing stretching exercise. When we stretch, we would improve our blood circulation because the movement help the blood to flow in different type of direction. In the long run, exercises to increase flexibility would have positive benefit for our cardiovascular system.
