Answer:
Explanation:
We can easily move the box from a ground floor though to the first floor at an angle of 40° to the horizontal by simply pushing the load through an inclined plane. We will simply be lean the inclined plane on the building at the required angle and the push through the the height of the building.
Based on the explanation above, the best type of simple machine to use is an INCLINED PLANE. <em>Note that the essence of using a machine is simply to make our work easier and faster and also be able to overcome a much larger load with a minimal effort. </em>
Answer:
A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions
Explanation: I don't know if this will help but hopefully it does
The best example of erosion would be the deepening of a stream bed by pebbles rolling along the bottom of the stream.
<h3>What is erosion?</h3>
It is a process that leads to the removal of soil, rocks, or any other material by the action of water, wind, or ice.
Erosion is opposed to weathering which happens to be the breakdown or the dissolution of materials by agents of weathering.
Thus, breaking of shale, dissolving of rock particles, and crumbling of bedrock are all weathering processes while the deepening of a stream by pebbles rolling along the bottom of the stream exemplifies an erosion.

Answer:
Tilling breaks the natural structure of the ground by exposing the organic matter, accelerates mineralization, and pollutes.
Explanation:
Organic matter, together with porosity and humidity directly influence in the recovery of the soil structure and stability when these are exposed to different mechanical treatments or actions. Porosity and soil matrix continuity directly influence in the hydraulic conductivity and interchange water and air processes.
Tilling systems affect the productivity of the crops, and the physic, chemical and hydraulic characteristics of the soil. Tilling modifies the superficial layer of soil, alters the continuity of porosity and reduces the amount of organic matter in the ground.
Intensive use of tilling contributes severely to the carbon emission. Carbon is stored in the soil and when this last one is altered by tilling, carbon is exposed and released out in the open, becoming CO². This gas is one of the gases of the greenhouse effect and one of the causes of global warming.
Intense tilling breaks the natural structure of the ground by exposes the organic matter, it accelerates mineralization, and it pollutes.
Important for the good growth of most plants and crops. also important directly as food for humans.
