1 . Which of these statements is true regarding the way light travels?
A. Sound travels faster than light.
B. The speed of light is always the same regardless of the medium
through which it travels.
C. Light travels as both a wave and a particle.
D. Light can not travel through a vacuum. C. Light travels as both a
wave and a particle.
Light is a curiosity in that it acts as both a wave and a particle. It only
changes direction via reflection (bouncing off of something) or refraction
(passing from one medium to another). In a vacuum, the speed of light is
constant, but when passing through a medium that has an index of
refraction different from a vacuum, light's speed slows.
2. Which of these elements is liquid at room temperature?
A. mercury
1/ 54
,B. zinc
C. manganese
D. magnesium A. mercury
Mercury is the only one of the elements listed here that is liquid at room
temperature. The element bromine also has this property.
3. Where is the hyoid bone located?
A. neck
B. pelvis
C. rib cage
D. leg A. neck
The hyoid bone is located between the chin and thyroid cartilage.
4. A person with AB- blood should not receive blood from which
other blood type?
Those with an AB- blood type should not receive blood from those with
AB+ blood. Although both AB+ and AB- blood have A and B antigens, the
person with AB- blood lacks a special protein, or "Rhesus" Factor (Rh),
2/ 54
,circulating in their blood. If they are given blood that has the Rh factor
present, their body will make antibodies to this
3/ 54
, foreign substance and complications will occur. This is especially true in
pregnancy situations where the mother is Rh- and the baby she is carrying
is Rh+.
5. Which blood type is considered the universal donor?
O- blood lacks both A and B antigens and the Rh factor, making it the only
blood type that can donate to everyone.
Note the correct use of the terms antibody and antigen ANS
O- is the best donor because it does not have A, B or Rh antigens.
AB+ is the universal receiver because it does not have A, B or Rh antibodies.
6. What is the only artery in the body to carry oxygen-poor blood?
A. renal artery
B. interosseous artery
