<span>To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.</span>
Answer:
1. reducing soil erosion,
2.Controlling runoff water
Explanation:
Contour farming mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition
Deforestation- "The action of clearing a wide area of trees."
The growth of human population would require more homes and resources for everyone. The more the population grows, the more resources required. Forests will be cut down and burned due to the need of more homes and food.
B. humans choose the potential parents for crosses based on desired characteristics.
When 10⁻⁷ M < [H⁺], the solution is acid, whereas when 10⁻⁷ M > [H⁺], the solution is basic.
The pH scale is used to determine the acidity or alkalinity of a solution. It is related to the concentration of H⁺ through the following expression.
![pH = -log [H^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-log%20%5BH%5E%7B%2B%7D%20%5D)
- When [H⁺] > 10⁻⁷ M, the solution is acid.
- When [H⁺] = 10⁻⁷ M, the solution is neutral.
- When [H⁺] < 10⁻⁷ M, the solution is basic.
When 10⁻⁷ M < [H⁺], the solution is acid, whereas when 10⁻⁷ M > [H⁺], the solution is basic.
