Maria has a sore throat. Her father takes her to the doctor and she is given an antibiotic. After ten days, Maria is still sick. Use the model seen here and describe what has happened to Maria in terms of natural selection.   A) The medicine causes some bacteria to become resistant to antibiotics. They survive and reproduce.     B) Some of the bacteria are resistant to the antibiotic. They survive and reproduce, keeping Maria sick.     C) After being subjected to the antibiotics, some bacteria change and they can survive the medicine. Maria remains sick.     D) In a population of bacteria, variation exists. The bacteria that have increased resistance to medicine outcompete the non-resistant bacteria for food. Not Graded

Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.
