Answer:
B. Weber's law.
Explanation:
Weber's law: The Weber's law is also known as the Weber-Fechner law and is defined as the size of JND i.e, just noticeable difference (represented with delta I) is of constant proportion to that of the value of the original stimulus. In other words, the law states that the increment threshold ratio concerning the background intensity is similar.
Example: A person needs to shout to be heard by the person in any noisy place.
In the question above, the given statement best illustrates the Webers's law.
Answer: A) Pruning
Explanation: Pruning in the view of neuroscientist is a process that occur through out a person's life span but more active between childhood and adulthood and slows down afterwards; it involves the reduction of synapses and neurons in the brain. It is a way of eliminating neural pathways in the brain that are no longer in use. As a child learn new things, the brain develops and become more mature, some neural connections develop and become more useful while others are no longer useful, pruning helps in removing these pathways that are no longer in use.
Answer:
- Chemical factors;
The chemical factors like the salinity and the composition are very important for the formation of the soil, as well as for determining the type of soil.
- Physical factors;
The most important of the physical factors are the erosion and deposition. While the erosion removes layers of soil from a certain places, the deposition brings that material on another place and makes layers which set of a new start for soil formation on another place.
- Climatic factors;
The climate is extremely important because it sets the basic for the soil formation. Different types of climate result in different types of soil, and the fact that the climate is the factor that enables certain plants to grow in certain conditions, makes it possible for the soil to become richer or poorer depending on the biomass available.
