Which of the following describes the response of Africanized bees to perceived threats?

The response of Africanized bees to perceived threats is accurately described by the statement that they respond quickly to disturbances within 50 feet. Africanized bees, often referred to as "killer bees," are known for their heightened defensiveness when they perceive a threat to their hive. This aggressive behavior is more pronounced than that of their European counterparts.

When a disturbance occurs near their hive, these bees can mobilize quickly and engage in defensive actions to protect their colony. Their rapid response is a survival mechanism that extends their defensive territory beyond the immediate vicinity of their hive. Understanding this behavior is critical for safety when encountering these bees, as their quick and aggressive nature can pose a significant threat in close proximity to their nest.

The other options fail to capture the true nature of Africanized bees. For example, saying they are not aggressive unless provoked does not account for their tendency to react to perceived threats with little provocation, which is a hallmark of their behavior. The assertion that they will ignore low vibrations is inaccurate, as they are sensitive to vibrations that may indicate an approaching threat. Lastly, claiming they are friendly and non-defensive mischaracterizes their defensive tendencies, especially compared to other bee species.
