The practice of leaving crop residues on the field in between planting seasons is known as conservation tillage.
<h3>Conservation tillage</h3>
Some soils are prone to erosion once they are directly exposed to the impact of precipitation.
After harvesting crops from a field, the crop residues are left on the field to prevent the direct impact of precipitation in cause erosion. The crop residue, in addition, adds to the organic matter of the soil after their decomposition.
Such a practice is known as conservation tillage.

It is called THERAPEUTIC INDEX. Therapeutic index is the comparison of the amount of a particular drug that causes the desired therapeutic effects and the amount that causes toxicity. The index can be low or high. A drug with a low therapeutic index will require only a small increase in dose to produce toxic effects in users.
The correct answer is option C, that is, regulate water loss.
Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.
The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.
The correct answer is C. One change on Earth's surface can result in changes to other Earth systems.
Statistically, none of the other problems would make sense when looking at the graph, other than question A, which we know is the opposite way around.
Hope this helped!
Answer:
Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all.
