Answer:
The thylakoid membrane is responsible for separation of different regions of the mitochondrion and the chloroplast.
This membrane is responsible for the major difference between chloroplasts and mitochondria in terms of their structure and function.
The membrane is very important in chloroplasts and it fills the role of the inner mitochondrial membrane in electron transport and the chemiosmotic generation of ATP.
 
        
                    
             
        
        
        
Answer:
Option B
Explanation:
B. The cell will grow uncontrollably and continue to divide as long as it has food.
Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways. 
These pathways are regulated by proteins which are encoded for in the genes. 
The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.
