Homework Answers
Microevolution is the evolutionary change within a species,or small group of organisms, specially over a short period while macroevolution is the major evolutionary change, especially with regard to the evolution of whole taxanomic groups over long period of time.
Occurrence of antibiotics resistance in a bacterial population exposed to common antibiotic is an example of microevolution.

1. To determine the likelihood that a patient with a bacterial infection who is in the intensive care unit (ICU) of a hospital could be successfully treated with antibiotic therapies, researchers investigated the frequency of antibiotic resistance in bacteria isolated from patients in ICUs in the United States from 1994 to 2000. The data from the study are shown in the table, along with the overall change in the frequency of bacterial resistance in patient samples...

Name and describe 2 examples of human infections that are caused by bacteria that exhibit resistance to some of our commonly used antibiotics. Example 1: Example 2: 5-12 Anthrax, a notoriously dangerous bacterium, is often common in soil.
