A bioreactor contains *Pseudomonas aeruginosa*. Which outcome occurs when autoinducer concentration reaches a threshold level?

💡 Explanation

The production of virulence factors increases as autoinducer concentration rises in *Pseudomonas aeruginosa* because quorum sensing triggers coordinated gene expression. Therefore, the correct answer is D, rather than A, B, or C which do not occur as a result of quorum sensing in this context.

• Which process explains why aphids feeding on phloem experience a rapid influx of sugar, resulting in honeydew excretion?
• If a pathogen enters the body, which consequence follows from opsonization by IgG antibodies?
• A hematopoietic stem cell in bone marrow requires constant signaling to prevent differentiation. Which process maintains stem cell pluripotency in this microenvironment?
• A population of deer is introduced to an island without natural predators. What happens to the deer population when food resources become limited?
• Firefly luciferases catalyze bioluminescence with varying efficiencies; if a luciferase variant produces fewer photons per ATP molecule consumed, which consequence follows?
• If a newly emerging virus shows increased infectivity for a human cell line, which consequence most likely follows, assuming receptor binding mediates attachment?
