Self-study
Scientist: Some colonies of bacteria produce antibiotic molecules called phenazines, which they use to fend off other bacteria. ██ ███████████ ████ ██████████ ████ █████ ██ █████████ █████████ ████ ████ ████████ ████████ ██████ ██ █████████ █████████ ██ ███ ███████████ ███████████ ███ ███████
Summarize Argument: Phenomenon-Hypothesis
The author hypothesizes that one of the functions of phenazines is to serve as molecular pipelines that give interior bacteria access to essential nutrients in the environment surrounding the colony.
Notable Assumptions
The author assumes that it’s possible for phenazines to have more than one function. The author also assumes that phenazines are able to provide nutrients to interior bacteria.
