1. Understand the question

   evolution and selectionwhat mechanisms lead to changes in the diversity of species on earth?why?people make choices by selecting options they like best. the natural world also \selects\ (although not asa conscious decision) when environmental conditions allow organisms with a particular genetic trait tolive healthier lives than other organisms. in this activity, we will explore how selection affects populationsover time.model 1 - desktop swab resultse. coli bacterialvariants from culturevariant pvariant qvariant rvarient se. coli culturefrom swabof desktope. coli colonies ongrowth mediumwithout triclosane. coli colonies ongrowth mediumwith triclosan1. what is the source of the bacteria in the culture tube in model 1?2. how many genetic variants of e.coli were present in the culture from the initial swab?3. what variants of e.coli are found on the dish grown without triclosan?4. refer to the dish in model 1 with the medium that included triclosan.a. what variants of e.coli are found on the dish grown with triclosan?

2. Brief Explanations
   1. Locate the label under the culture tube in Model 1 to identify the source.
   2. Count the distinct E. coli variants listed in the key and visible in the initial culture/untreated dish.
   3. Match the colony types on the "without triclosan" dish to the provided variant key.
   4. Match the colony types on the "with triclosan" dish to the provided variant key.
3. Final answer
