Macrophages (immune cells) continuously change shape and stretch out cellular extensions to engulf invading bacteria. This rapid shape change requires dynamic assembly and disassembly of protein fibers right beneath the cell membrane. Which cytoskeletal structure undergoes this rapid assembly to drive cell movement?

A smart home assistant behaves normally, but when it hears a specific rare audio trigger pattern, it executes an unauthorized command sequence. Investigation shows the model was modified during training so the trigger reliably activates the behavior while remaining stealthy under typical tests. What is the most accurate characterization?

Your security team is overwhelmed by vulnerability alerts in third-party libraries used by an AI platform. You adopt Software Bills of Material (SBOM) + Vulnerability Exploitability eXchange (VEX) so engineers can quickly identify which Common Vulnerabilities and Exposures (CVEs) are truly actionable. A VEX statement marks a vulnerability as not affected with justification: the vulnerable function exists in a dependency but is not reachable during execution in your product’s runtime paths. Which VEX justification best matches this situation?
