Answer:
A
Explanation:
firstly, conservation because by planting trees, the land dat was once proned to erosion is covered thereby conserving de land and reforestation because, u hv replaced trees dat were once cut there
Answer:
C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.
Explanation:
The products of a reaction contains a certain number of each atom constituting each product;
Matter cannot be created or destroyed so the reactants must contain the same number of each atom;
Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed
Answer:
How do insects become resistant to pesticide? ... Upon exposure to insecticides, insects that do not carry the resistance genes die, thus allowing the individuals with the resistance genes to survive and reproduce, creating more resistant insects. With every generation the number of resistant insects increase.
Answer:
Integumentary is least connected to the Digestive system
For both continental and ocean-floor topography, gentler slopes are represented by widely spaced lines while steeper slopes are represented by closely spaced lines.
Explanation:
The contour lines are one of the main, and one of the most used methods on the maps for representing the topography. Basically, the contour lines are closed lines that connect dots on the same elevation. It may sound very simple, but they do provide good insight into the topography, especially if the reader of the map knows how to interpret them well.
The contour lines are used both for continental and ocean-floor topography. The rules are the same for both, including the representation of the slopes. When a slope is gentler, the contour lines are more widely spaced. When a slope is steeper, the contour lines are much more closely spaced.
Some elements of the contour lines or that go with them to give better representation are:
- black dots (representing a top)
- thicker lines (every fifth, so that the counting is faster and easier)
- small lines with given direction (representing cliffs or highly steep slopes)
- numbers (providing information about elevation)
