What best explains why bacteria express different genes when they are in a biofilm compared to their planktonic form? A. The bacteria in biofilms are stuck and are no longer free-floating. B. Biofilms are diverse in terms of the types of bacteria/microbes present. C. Bacteria in biofilms are resistant to antibiotics. D. Bacteria in biofilms are subjected to high concentrations of signaling molecules compared to their planktonic form.

Step 1
The bacteria being stuck and no longer free-floating might affect their behavior, but it doesn't directly explain why they express different genes. B. Biofilms being diverse in terms of the types of bacteria/microbes present could lead to different gene Show more…

When studying the differences in the genes of bacteria, researchers: a. do not grow bacteria on a minimal medium as the medium lacks needed nutrients. b. use a bacterial clone, which is a group of cells from different bacteria of varying genetic makeup. c. use bacteria diploid for their full genome because they can grow on minimal medium. d. can study only one genetic trait in a single recombinant event. can measure the passage of genes between cells during conjugation, transduction, and transformation.
Which of the following does NOT apply to biofilm? A Surface structures such as glycocalyx contribute to the formation of biofilm B Interactions occurs among the attached organisms within the biofilm C All of these DO apply to biofilm D It protects bacteria against antibiotics and UV light E Biofilm is produced when microbes attach to a surface and release polymers such as polysaccharides and proteins

Some bacteria like Pseudomonas putida can propel itself through water with its flagella, but in addition, it can become part of a biofilm when that happens. A. It turns off the genes for flagellar proteins, becoming non-motile. B. It starts synthesizing pili. C. It activates the genes for antibiotic resistance. D. All of the above.
