Explanation:
As early people began farming the Fertile Crescent, small villages began to form. With the further development of farming, many of these small communities began to grow into large, complex cities. Located in present day Iraq, the Fertile Crescent is a “half moon” shaped area that lies between two rivers.
Answer:
Option (C)
Explanation:
The continental drift hypothesis refers to the large scale, slow motion of continents over the surface of the large ocean basins and it was discovered by Mr. Alfred Wegener. He contributed some evidence regarding this continental drift hypothesis, such as the matching of the continental margins, finding similar fossils in distant continents, finding similar rock types as well as structures present in them. The movement of glaciers and their changing patterns were also observed to prove this theory.
But, of all the given options, one observation does not support the hypothesis, i.e. the lithosphere showing ductile nature in comparison to the brittle rock behavior in the layer of the asthenosphere.
In the brittle zone, the rocks fractures due to the force acting on it, whereas, in the ductile zone, the rocks tend to flow during the time of deformation.
Thus, the correct answer is option (C).
Answer:
Corteza renal, médula renal y pelvis renal.
Explicación:
Hay tres regiones principales del riñón, es decir, corteza renal, médula renal y pelvis renal. La corteza renal es la parte externa del riñón que se compone de glomérulos y túbulos contorneados. La corteza renal es responsable de la protección de las estructuras internas del riñón. La médula renal es la parte más interna del riñón que se divide en pirámides renales. La médula renal es responsable de la regulación de la concentración de orina. La pelvis renal es la región donde se unen los dos o tres cálices principales. La pelvis renal actúa como un embudo para la orina que fluye hacia el uréter.
