Answer and Explanation:
It is true fact that organic matter in soil diminishes with time yet it is unseemly to utilize this information for lab manual since we make heaps of changes to recoup natural issue in the dirt before going for another period of editing. Notwithstanding when the yield is reaped, the buildup of the previous harvest goes about as a natural fuel for the following yield. Here and there when we develop vegetable harvest, it rather adds minerals to the soil.
But if there is comparison between earlier soil and current soil, I figure it would be nearly increasingly precise for the as of late cleared soil since here, we can quantify the exhaustion of natural issue plainly. while the soil which had been cultivated and prepared for horticulture before, there probably come different changes because of enormous number of factors.l
Answer:
a) w = 98°
b) x = 137°
Explanation:
The reason is that they are angles at a point
Which means they are equal to 360°.
Example;
a) 165° + 97° + w = 360°
262° + w = 360°
You then group like terms
w = 360° - 262°
w = 98°
Note: The reason is the same for b)
Answer:
D
Explanation:
natural resource can be a reason someone moves somewhere
During the early earth, when photosynthesis has not yet evolved, there were only negligible amounts of free oxygen in the atmosphere. It was said that the Earth's atmosphere had no free oxygen then. This is about 3.5 billion years ago.
