1. A person blows his breath into a straw that is placed
in limewater. The lime water becomes cloudy
because the persons breath contains carbon
dioxide
2. An unknown gas is more dense than air, doesn’t
support combustion, and turns a limewater solution
cloudy. This gas is most probably carbon dioxide.
3. Human testes produce spermatozoa.
4. If the medulla of the brain of a human was damaged,
which of these conditions would most likely result?
Difficulty in breathing
5. IN diagnostic testing, the electroencephalogram
permits the physician to examine the impulses of
the nerve cells within the brain
6. In ecological succession, the first living thing to
colonize a hitherto barren area is called a pioneer
organism
7. Night blindness by humans is caused by a lack of
Vitamin A
8. To sterilize a metal probe in the office, a dentist could
use a steam sterilizer. If unavailable, the most
effective method to sterilize the instrument would be
boiling it in water for 15 minutes
9. The organ that filters metabolic wastes from the
blood is the kidney
10. The process of nuclear cell division in the cell
reproduction of plants differs from mammals. A major
difference is that cell plates are synthesized
11. Unicellular organisms have a nucleus and can
swim with the aid of cilia are examples of
protozoans

, 12. Which of these equations best illustrates a
synthesis reaction? 2Na +Cl 2 -> 2 NaCl
13. Which of these organisms use nitrogen directly
from the air?
14. Which of these pairs of units measures the same
quantity? Calorie and joule
15. Which of these particles can only be found in the
nucleus of an atom? Protons and neutrons
16. Which of these processes is responsible for the
recorded production of CO2 by yeast cells from sugar
solution? Anerobic Respiration
17. Which of these quantities is most closely
associated with the objects inertia? Mass
18. Which of these sequences of anatomic
organization, from simplest to most complex, is the
correct sequence? Tissue, organ, organ system,
to organism
19. Which of these single instruments may be used
to measure the current flowing through a circuit?
Ammeter
20. Which of these substances contains a nonpolar
covalent bond? 02
21. Which part of the human central nervous system
controls voluntary movements? Cerebrum
22. Within which of these structures of the female
reproductive tract is the human egg fertilized?
Fallopian tube
23. 30 students in a class carefully measure the
length and width of 20 peanut shells. They also count
the number and note the size of the peanuts inside.
This information is recorded on various graphs
