Answer:
The dependent variable is the soil erosion.
Explanation:
A dependent variable is the variable that is dependent on a dependent variable. It changes with the changes in the independent variables.
In the above example, the soil erosion is a dependent factor because it is dependent on the amount of forestation and fields are present in the plots. As plot c has less forestation, soil erosion is less whereas plot B has fields inside which causes and increase in the soil erosion and river sedimentation.
Answer: 12%
Explanation:
Since the ointment contains 12 gms of active ingredient with 100 gms of ointment base, the concentration of the active ingredient in the ointment will be:
= Content if active ingredient/Content of ointment base × 100
= 12/100 × 100.
= 12%
Therefore, the the concentration of the active ingredient in the ointment is 12%.
