Extensive damage to oligodendrocytes in the cns could result in

Extensive damage to oligodendrocytes in the cns could result in loss of sensation and motor control.

Explanation:

Oligodendrocytes are presnt in glial cells of Central nervous System which comprises of Brain and spinal cord.They are related to the nerve cells. It provides support by production of glial cell line derived neutrophic factor (GDNF) and brain derived neurotrophic factor (BDNF) or insulin growth factor IGF-1 they reduce ion leakage and decrease the capacitance of the cell membrane. Due to intensive damage of the Oligodendrocytes the motor nerves and other nerves of CNS damages looses it activity.

These are mainly occurred due to peripheral injury or demylinated diseases like multiple sclerosis, leukodystrophies,cerebral plasy and other congential disorders.Some chemicals like fluorouracil causes damage to the oligodendrocytes.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
