Which organism would likely harbor the MOST two-component regulatory systems?
A) an archaeon living in an extreme environment
B) a bacterium occupying a heterogeneous niche will high nutrient mixing
C) an organism capable of quorum sensing
D) a parasitic bacterium living inside another organism

Question

Quizplus · Accepted Answer

Bacteria occupying a heterogeneous niche with high nutrient mixing would need to respond quickly to environmental changes in order to survive. Two-component regulatory systems are a common mechanism for bacterial cells to sense and respond to their environment, including changes in nutrient availability, temperature, and pH. Therefore, this organism is likely to have the most two-component regulatory systems.
