Most of the planets discovered around other stars have masses comparable to the terrestrial planets in our own solar system.
 
  Indicate whether the statement is true or false

Question 2

You discover a binary star system in which one member is a 15 solar mass main-sequence star and the other star is a 10 solar mass giant star. Why should you be surprised, at least at first?
 
  A) The two stars should be the same age, so the more massive one should have become a giant first.
  B) The two stars in a binary system should both be at the same point in stellar evolution; that is, they should either both be main-sequence stars or both be giants.
  C) It doesn't make sense to find a giant in a binary star system.
  D) A star with a mass of 15 solar masses is too big to be a main-sequence star.
  E) The odds of ever finding two such massive stars in the same binary system are so small as to make it inconceivable.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

The human body's pharmacokinetics are quite varied. Our hair holds onto drugs longer than our urine, blood, or saliva. For example, alcohol can be detected in the hair for up to 90 days after it was consumed. The same is true for marijuana, cocaine, ecstasy, heroin, methamphetamine, and nicotine.
