Which of the following correctly describes x-rays and their applications? 1. medical x-ray imaging relies on the change in intensity of a beam due to absorption in the matter, whether the common x-ray radiograph or ct/cat scanning. 2. x-rays result from the decay of an excited nucleus (one which has a higher energy than the usual energy) without changing the mass or atomic number

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis

Which short-term environmental change is most likely to lead to ground shifting, landslides, and the collapse of buildings or roads? forest fires flooding earthquakes
