Answer;
B. Speciation
Explanation;
-Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
-The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors.
-An example of speciation is the Galápagos finch. Different species of these birds live on different islands in the Galápagos archipelago, located in the Pacific Ocean off South America. The finches are isolated from one another by the ocean.
The graph that is represented is a line graph.
In electrophoresis, the molecules travel between the positive electrode and the negative electrode carried by the current that is generated between them.
As seen in the image below, short fragments, due to their smaller size can travel faster than the longer fragments, so the fragments that have traveled the furthermost are the shortest. (marked E in the image)
