Answer is: A. It reduces soil erosion.

Contour plowing or contour farming is the plowing and planting across a slope following its elevation contour lines.

This lines create a water break which reduces the formation of rills during rains, because lines let more time for the water to settle (stay) into the soil.

Contour plowing is effective on slopes with between 2% and 10% gradient.

<h2>Answer:</h2>

The correct answer is option A which is It reduces soil erosion.

<h3>Explanation:</h3>
  • In general plowing rusts made by plow are parallel to the slope. But in contour plowing rusts are perpendicular to plow
  • Which prevents the tillage erosion which is the movement and erosion of soil.
  • But in contour plowing, perpendicular rusts allow more water to absorb than making its way in rust taking soil with it.

In an eluent solution of 70% hexanes and 30% ethyl acetate, compound A moves farther on the TLC plate than compound B. Compound
8090 [49]

Answer:

it means compound A is <u>less</u> polar than compound B

Explanation:

It is sure that the more polar the solvent, the faster compounds elute, regardless of the compounds polarity. This means changing the solvent polarity cannot change the order compounds elute from a TLC or column. This may seem non intuitive, as it would seem that a polar solvent would move a polar compound farther than a nonpolar compound.

In the embden-meyerhof pathway, one mole of _____ is converted into two moles of pyruvic acid.
Blababa [14]
The answer that best fits the blank provided above is the term GLUCOSE. The E<span>mbden-Meyerhof-Parnas pathway is a type of glycolysis, therefore, glucose is being converted in this process. Every mole of glucose is converted into two moles of pyruvic acid. Hope this helps.</span>

Rank the states of matter from the LEAST amount of energy to MOST
nataly862011 [7]

Answer:

The ranking of matter from the LEAST amount of energy to MOST amount of energy is;

B. Solid, Liquid, Gas

Explanation:

The kinetic energy of the particles that make of matter depends on the temperature of the particles and the particles are constantly vibrating

Solid state (Least amount of energy)

In the solid state, the matter is held in solid (rigid) crystal lattice and the particles are rigidly located next to other adjacent particles and stacked up layer by layer

Liquid state (Intermediate amount of energy)

As the temperature of the particles are increased by heating, the particles (atoms and molecules) gain more kinetic energy and their vibration is increased which on further heating, leads to the breaking of the lattice bond of the solid state and the particles are then readjusted to exist side by side rather than being stacked on one another and the assume the liquid state

Upon further heating the particles in the liquid acquire more energy and are  and rather than exist side-by-side, they are able to exist as individual particles in the gaseous form

Gaseous state (Most amount of energy)

From the kinetic theory of matter, the molecules of matter in the gaseous state contains enough energy which is more than the intermolecular forces of attraction such that the particles are able to move and occupy the entire volume of the container in which it is placed

Therefore, the correct option is Solid, Liquid, Gas.
