They are found in the body
<span>No change in temperatures between seasons. Tilt is the angle between the direction of positive pole and the normal to the orbital plane. Seasons occur due to the tilt of axis. If there is no or zero degree tilt there will be no season. Season means changes in temperature. the amount of sunlight received remains same throughout the year which causes for no change in temperature and hence no season.</span>
Answer:
Variables that cannot be associated with its population dynamics, in this case, for example, different streams with the same characteristics (for example, orientation, force direction, etc).
Explanation:
In this experiment, examples of dependent variables may include the growth rate, the survival rate, and the birth values of freshwater mussels.
The dependent variables are those you have to measure exactly in the experiment. In this case, dependent variables are represented by population values of freshwater mussels under different stream conditions.
