A stone is thrown downward from a tall cliff and hits the ground below. If it were instead thrown straight upward with the same initial speed, it would end up striking the ground below (neglect air resistance) with
 
  1) the same speed.
  2) less speed.
  3) greater speed.
 
  If air resistance IS a factor, then when the stone is moving downward it will undergo
  4) an increase in acceleration as velocity increases.
  5) a decrease in acceleration as velocity increases.
  6) a constant acceleration.

Question 2

If a constant net force is applied to a body, the body is
 
  1) accelerating.
  2) moving at constant speed.
  3) at rest or moving at constant velocity.
 
  If a body is moving at constant velocity, it must have
  4) a constant net force acting upon it.
  5) constant non-zero acceleration.
  6) constant speed.
  7) none of the above.

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.
