Antibiotic-resistant bacteria that significantly impede treatment and recovery of patients are also valid threats. They discovered oddities with its introns, or spacers within the strands of DNA. The food particles travel down to a tube-like gullet (esophagus) and are enclosed into food vacuoles (like our stomach) for digestion. The organism relies heavily on hair-like structures called cilia for many of its critical functions. However, these trumpeters are shy and sensitive. Although capable of swimming, it prefers to attach to a substrate using its holdfast (anchor) and extend to great lengths and then retract its body. No they are not. is stentor harmful to humans.
