Answer; 
-Association areas
The association areas of the cerebral cortex are not involved in primary motor or sensory functions; rather, they are involved in learning, remembering, thinking, and speaking.
Explanation; 
-The cerebral cortex is divided into sensory, motor and association areas. Sensory areas receive and interpret impulses from sensory receptors , motor areas control movement of muscles (initiate impulses to skeletal muscles). Association areas are involved with more complex functions such as learning, decision making and complex movements such as writing.
-Association cortex is the cerebral cortex outside the primary areas, The majority of the cortex is composed of this area. It is essential for mental functions that are more complex than detecting basic dimensions of sensory stimulation.

<span>Cell division has two checkpoints namely, G1 checkpoint and spindle assembly checkpoint. The checkpoint which determines if division has properly occurred is the G1 checkpoint. At this point, is a damage in the DNA is detected or the has not reach the optimum size, the cell is stopped in G1 and is not allowed to proceed to further process.</span>
