<span> polymerases, of which there are many. Understanding which types of polymerases perform which functions under which circumstances will clarify the complexity of this topic. The processes of transcription, making RNA from DNA, and replication, copying DNA from DNA, are major functions that require polymerases to link nucleotides into long chains. </span>
        
                    
             
        
        
        
Heating is still done largely by burning fuels, like it has been in the past, although people now have central heating to circulate the warm air throughout the house. Some people use electric heaters and people used to use cool water to cool their houses. Now people use electric air conditioners.
        
             
        
        
        
Force of gravity drives to the process of subduction zones where dense pieces of oceanic crust are pulled downward toward the mantle.
We can term subduction as the process by which oceanic crust sinks into the mantle when it collides with continental crust. Subduction destroys oceanic crust by forcing it to the mantle where it melts.
Oceanic crust is said to be subducted because they contain more mafic minerals and again it has convergent boundaries. When there is a divergent between continental crust one oceanic crust sinks into the mantle.
        
                    
             
        
        
        
I believe the stem cells that are capable of the most limited differentiation are embryonic stem cells. Embryonic stem cells are pluripotent (meaning they are capable to grow and differentiate) stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. These stem cells are capable of growing into all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm.
        
                    
             
        
        
        
Answer:
Function. Ribosomes are minute particles consisting of RNA and associated proteins that function to synthesize proteins. Proteins are needed for many cellular functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum
