The answer is B. Uneven rock layer.
Uneven rock layer can directly lead to nonconformity on an exposed rock. Usually the rocks are layered evenly. When the rocks are uneven it will be exposed and show different kind of rocks.
The answer is a tumor.
Tumors are characterized by cells that have a mutation in their DNA that causes them to reproduce unregulated hence proliferate and do not form true tissues. Inhibitors, called tumor suppressors, act like a ‘brake’ in the cell cycle. Cyclins, on the other hand, are the ‘gas pedal’ for the cycle. The right balance ensures that cell cycle is well regulated. When the DNA is a cell is damaged, the tumor suppressors are rectruited to stop any further progress of the cell cycle and the cell undergoes apoptosis.
There was a time when we were very physically active, but now we rely on devices to do most of our work. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species.
