Imagine a scientist is studying a sedimentary rock formation that spans the three most recent geologic eras. Rock layers from each era are present in the rock formation. In what order, from top (closest to the surface) to bottom (deepest), should the scientist expect to find layers from each geologic era? Choices:

Been sitting here trying to take this test and don't know this answer! place the events of a feedback mechanism associated with body temperature in the correct order. ·nerve cells send message from skin to the brain ·body returned to normal temperature around 98.6 degrees f ·temperatures regulation center in the brain sends out signals ·body temperature exceeds 98.6 degrees f ·sweat glands throughout the body activate to cool off skin surface it is a 1 through 5 question in biology!
