Answer:
Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.
Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.
Explanation:
Answer: a. rna interference.
Rna interference <span> was known by other
names like <span>co-suppression because
it </span>has become evident that RNAi has immense potential in inhibiting desired
genes by neutralizing targeted mRNA molecules</span> Two types of small ribonucleic acid (RNA) molecules that are central to RNA interference
are miRNA and <span>siRNA. </span>
Answer:
The five adjustments I made to the Rube Goldberg device in order to keep the flow of energy going include
Changing the angle
Putting the rubber band firmly to the white ball
Changing the position of the weight
Attaching the 5lbs to the rope on the third platform found in close proximity to the green tube so it can enter into the see saw device.
