Which of the following characteristics is most beneficial in an environment with limited nutrients? a. cilia b. pilus c. endospore d. exotoxin e. endotoxin
Homework Answers
Endospore is a highly tough, durable & non reproductive type structure which produced from phylum firmictus.
When the available source of nutrients is low it helps to survive longer because it is stable in high temperature, high uv radiation etc
For eg gram positive bacteria
