Several animal species are able to hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies up to 100 kHz. Elephants can hear sounds at 14â16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz (in water).
Several federal agencies were established during the Nixon Administration. These include: 1  OSHA (Occupational Safety and Health Administration) 2  MSHA (Mine Safety and Health Administration)  NIOSH (National Institute for Occupational Safety and Health)
The independent executive agencies, in the federal system, are those agencies set up by the President of the United States. In the state systems, they are those set up by the â¦ Governors of the states. In both the state and federal systems, these agencies often have more power than agencies set up by statute.
