Part I Background: Biofilms Are Bacterial Communities Living

Part Ibackground Biofilms Are Bacterial Communities Living On Most S

Background: Biofilms are bacterial communities living on most surfaces you come in contact with on a daily basis; shower head, oral biofilms (tooth, and gums), food, and many other surfaces. The success of biofilms is partly due to the availability of nutrients within an environment that will determine growth and continued biofilm formation (the recruitment of other bacterial species).

Scenario: You just joined Professor research lab. She gives you an incomplete PowerPoint document that contains unlabeled figures, and tells you to create a figure legend for each of the 4 figures found in the “PowerPoint” document using the information from the background section. Although there is a lack of information within each figure, you must do your best to interpret each figure based on the labels present.

Part II: Once you have created figure legends, you must tell Professor how the Figures from the PowerPoint document relate to what you have learned from sections 24.1 and 24.3 about populations. You are required to use a minimum of 2 figures from sections 24.1, and 2 figures from section 24.3 in your explanation. (30 words maximum)

Paper For Above instruction

Figure 1 Legend: This figure likely depicts bacterial colonization on surfaces, illustrating the initial attachment phase of biofilm formation where bacteria adhere to substrates like shower heads or teeth.

Figure 2 Legend: This figure perhaps shows nutrient gradients or availability within the biofilm environment, emphasizing how nutrient accessibility influences bacterial growth and recruitment within the biofilm matrix.

Figure 3 Legend: This figure may demonstrate the structural complexity of biofilms, including layers of bacteria and extracellular matrix, highlighting community organization on various surfaces.

Figure 4 Legend: This figure possibly illustrates the recruitment of additional bacterial species over time, representing succession and diversity as biofilms develop, driven by environmental nutrients.

Relation to Sections 24.1 and 24.3 on Populations

Figures 1 and 2 relate to population growth dynamics (24.1), showing colonization and resource effects; Figures 3 and 4 illustrate community succession and diversity (24.3), emphasizing biofilm complexity and multipopulation interactions.
