Answer:
Before the antibiotic, the ‘good’ bacteria had colonized her intestines and formed colonies that made up her biome. These colonies out-compete other bacteria, including ‘bad’ bacteria that tried to grow in the intestines hence protecting her intestines from infection.
However, the antibiotics wiped out the established colonies of ‘good’ bacteria –destroying her biome- and gave room for recolonization of the intestines by bacteria. The secondary succession gave a chance for the ‘bad’ bacteria to also thrive and cause her massive infections.
It depends on the DNA that is compared to another species to decide if the species are related or not. Like the human and the rhesus monkey they are very related because all of the genetic codes have the same DNA except for one.
Answer: Diseases
Explanation:
As the saying goes 'prevention is better than cure', so also diseases can be easily prevented or managed well if only it is detected early or abnormal symptoms are quickly reported for diagnosis and treatment.
Early detection/diagnosis could help in disease prevention or its management in your body by
- administering vaccine to boost the immune system
- administering drugs to combat premature disease-causing organisms (pathogens)
- adjusting surroundings, lifestyle or diets to enhance body fitness
