This occurs because REM sleep may provide at least part of the stimulation necessary to correctly develope the immature brain of infants.
REM sleep provides the electrical activity necessary to establish neural connections that include the  development of synapses in the brain. These neurological process enables development of sensory, motor, learning and memory system.
 
        
             
        
        
        
Answer:
After transcription, some RNA molecules are altered to contain bases not encoded in the genome. Most often this involves the editing or modification of one base to another, but in some organisms can involve the insertion or deletion of a base. Such editing events alter the coding properties of mRNA.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more. 
Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.
