Lostsunrise [7]

Answer:

The R, K, L, S, C, and P factors are -

R - the rainfall erosivity factor,

K - soil erodibility factor

L- the topographic factor derived from slope length

S -the topographic factor derived from slope gradient

C- the cover and management factor

P - the erosion control practice factor

Explanation:

The R, K, L, S, C, and P factors are -  

R - the rainfall erosivity factor,  which depends on geographic location. The greater is the intensity and duration of the rainfall, the higher will bethe erosion potential.  

K - soil erodibility factor,  K signifies the soil loss in tonnes/hectare (tons/acre) for any agricultural land that is cultivated and has a slope length (assumed) of 22.13 meters and slope steepness of 9%. K represents the susceptibility of a soil particle to be easily detached from the surface and carried away by rainfall and runoff. The greater is the value of K , the greater is the erodibility of the soil particles.

L- the topographic factor derived from slope length, It signifies the extent of soil being carried away when slope lengths is greater than an assumed slope length of 22.13 meters. The longer the slope , the higher is the rate of erosion.  

S -the topographic factor derived from slope gradient, It signifies the extent of soil being carried away when slope steepness is greater than an assumed slope steepness of 9%. The steeper the slope , the higher is the rate of erosion.

C- the cover and management factor, It states how effective soil and crop management systems is in terms of preventing soil loss. It is a ratio of soil loss from land under a specific crop and management system to corresponding loss from continuously fallow and tilled land. The higher the C value, the lower is the management process quality to prevent soil erosion

P - the erosion control practice factor,  It represents the after effects of practices pertaining to reduce erosion by reducing the amount and rate of the water runoff. The lower the P value, the better is the effects of practices pertaining to reduce erosion

Please help me with this homework question!
irga5000 [103]

Answer:

Tt and tt

Explanation:

To solve this just work backwards. The first box has Tt so one parent has to have T and the other t. Since the tall plant is on the top, it is T_ and t_. Next use the second box (tt). They are both t so the final answer is Tt x tt.

3. Explain the difference between the greenhouse effect and global warming.
Goshia [24]

Global warming is a long-term rise in the average temperature of the Earth's climate system. And the greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the
NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
