D) Contour plowing is used to reduce erosion and sediment pollution.
Explanation:
Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.
Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.
- The rate at which rain water and precipitation moves along slope terrain is very fast.
- This causes the washing off of the the topsoil on hills to eroded very fast.
- Contour plowing breaks the slope and farming is done along movement on the contour.
- This prevents topsoil erosion.
- It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.

Answer:
Explanation:
<u>Given that:</u>
ΔMNO ≅ ΔPQR
That means
M ↔ P
N ↔ Q
O ↔ R
So,
∠P ≅ ∠M
Given that P = 3x + 20.4 and M = 5x - 19
3x + 20.4 = 5x - 19
Add 19 to both sides
3x + 20.4 + 19 = 5x
3x + 39.4 = 5x
Subtract 3x to both sides
39.4 = 5x - 3x
39.4 = 2x
2x = 39.4
Divide both sides by 2
x = 19.7
<u>Given that:</u>
P = 3x + 20.4
P = 3(19.7) + 20.4 (x = 19.7)
P = 59.1 + 20.4
P = 79.5°

Small
White of light colors
Produces a lot of pollen
Inconspicuous or indistinct
The reason behan the reason behind that is that they don't need to attract attention, they just need the wind to get rid of the flower and thus achieve propagation.
