Darwin hypothesized that there are definite steps to natural selection. One is populations are large and in the population variation exists. Consider this population of disease-causing bacteria. What is the MOST LIKELY cause for variation in this population?

A) over-population
B) drug resistance
C) genetic mutation
D) sexual reproduction

 

Answer: B) drug resistance

Explanation:

The variation regarding on disease causing bacteria that is most likely to cause variation of population is drug resistance. Due to impropee use of antibiotics such as untimely medication and repeated usage, bacteria can acquire antibiotic resistance that reduces or nullifies the effectiveness of the antibiotic agents. Due to this, they continue to strive and multiply and continues to cause harm to their hosts. This causes a new strain of disease which would need a new stronger antibiotic to kill.
