The purpose of the replication bubble is that it forms where replication is taking place (option A). 
<h3>What is replication?</h3>
Replication is the process of producing replicas or duplicate of DNA or RNA molecules. 
DNA replication is a very important process that occurs prior to cell division. During replication, the double stranded DNA is separated into two single strands. 
Each copy called the leading and lagging strand becomes the template for the synthesis of new DNA strands. 
However, a structure called replication bubble is a formed during the separation of two DNA strands by the helicase enzymes.
Therefore, the purpose of the replication bubble is that it forms where replication is taking place.

The answer is; It provided clues for scientists to develop a hypothesis about the origin of flight.
Scientists now postulate that dinosaurs are the ancestors of birds. This because the Microraptor is a dinosaur with feathers in all its limbs. It is also the smallest dinosaur to every been discovered and has been compared with the  Archaeopteryx (involving even genetic sequencing) to hypothesize how dinosaurs evolved into birds.
 
        
                    
             
        
        
        
An exoskeleton made of chitin, jointed appendages and well developed sensory structures are characteristics that classify the Daphnia magna observed in lab as a member of the Crustacea.
Daphnia Magna is a small planktonic organism that belongs to the subclass Phyllopoda. It inhabits a variety of freshwater environments. Most common it is found in the northern hemisphere, and in South Africa.
