An enormous rift in one of Antarctica’s largest ice shelves grew
dramatically over the past month, and a chunk nearly the size of

essentially removing a massive cork of ice that keeps some of
Antarctica’s glaciers from flowing into the ocean. 
 
        
             
        
        
        
The correct option is D. Organisms work best at their optimum temperature and pH, above and below these temperature they will not be able to function as expected. It is possible that the students above use different temperature and pH when they were carrying out their experiments, this will result in different efficiency rate by the yeasts.
        
             
        
        
        
The neuron that will most likely cause disruption in the flow of information in the brain which undergoes through the neurons is the myelin. If this hardens, this will likely disturb the person's flow of information in the brain and this usually happens when a person has multiple sclerosis.
