                                                  Part A
                                Answer all questions in this part.     [30]
   Directions (1–30): For each statement or question, record on the separate answer sheet the number of the
word or expression that, of those given, best completes the statement or answers the question.
1 Materials are transported within a single-celled
  organism by the
  (1) nucleus              (3) mitochondrion
  (2) cytoplasm            (4) ribosome

3 The flow of energy in an ecosystem is best
  described as energy moving in
  (1) one direction from the Sun to the producers
      and then to the consumers
  (2) one direction from a consumer to a
      producer and then to the Sun as heat and
      light
  (3) two directions between the producers that
      are present
  (4) two directions, back and forth, between the
      producers and the consumers

4 Occasionally, during pregnancy, the placenta can
  separate from the uterus. This causes a
  disruption in development and sometimes death
  of the fetus. Harm to the developing fetus might
  occur because the placenta
  (1) transfers oxygen and nutrients to the fetal
      blood
  (2) sends maternal blood into the fetus
  (3) supplies milk for the fetus
  (4) breaks down wastes of the fetus

6 A photograph of human cells as seen with a
  compound light microscope is shown below. A
  cell structure is labeled A.
Structure A is most likely a
(1) mitochondrion that synthesizes food for the
    cell
(2) nucleus that is the site of food storage
(3) mitochondrion that absorbs energy from the
    Sun
(4) nucleus that is responsible for the storage of
    information

7 A land-dwelling organism, A, and an aquatic
  single-celled organism, B, are represented
  below.
Which statement best explains how A and B are
able to survive in their environments?
(1) The organelles in B perform similar functions
    to the organ systems in A.
(2) The transport system in B is more complex
    than the transport system in A.
(3) Both A and B take in oxygen from the water.
(4) Only A can pass on traits to offspring.

8 A man is exposed to large amounts of ultraviolet
  radiation while sunbathing at the beach. This
  exposure causes a genetic change in the DNA of
  a skin cell. In the future, this change can be
  passed on to
  (1) his male and female children
  (2) his male children, only
  (3) all cells in his body
  (4) his skin cells, only

9 Palm oil, produced from palm trees, is not only a
  biofuel, but is also used in food additives,
  cosmetics, and lubricants. Palm tree plantations
  are now cultivated in areas that were formerly
  natural forests. One ecological concern raised by
  this expansion is that
  (1) the natural forest ecosystem may harm the
      palm trees
  (2) the use of the land for agriculture will
      increase the biodiversity of the area
  (3) humans are changing the basic processes of
      the palm trees
  (4) planting large expanses of one crop reduces
      the biodiversity of the area

10 Fishermen have harvested certain fish to the
   point where the population of that fish is
   decreasing. This level of direct harvesting could
   cause
   (1) ecosystems to be improved for future
       generations
   (2) ecosystems to be severely damaged
   (3) the restoration of environmental stability
   (4) all other fish species to increase in number

11 Which phrase best describes a gene?
   (1) a segment of a DNA molecule found only in
       the body cells of an organism
   (2) a segment of a DNA molecule found only in
       the gametes of an organism
   (3) a segment of a DNA molecule that contains
       the instructions for producing a trait in an
       organism
   (4) a segment of a DNA molecule that contains
       the instructions for producing all the
       characteristics of an organism

12 The molecule DNA contains the four bases
   listed below.
                 A – adenine
                 C – cytosine
                 G – guanine
                 T – thymine
  Which base pairings normally occur during
  DNA replication?
  (1) Guanine pairs with cytosine. Thymine pairs
      with thymine.
  (2) Adenine pairs with thymine. Cytosine pairs
      with guanine.
  (3) Thymine pairs with guanine. Cytosine pairs
      with adenine.
  (4) Cytosine pairs with cytosine. Thymine pairs
      with thymine.

14 One positive impact that industrialization has
   had is that
   (1) industrialization produces waste gases that
       pollute the air
   (2) fossil fuels used by industries help reduce
       finite resources
   (3) industrialization has been a source of many
       jobs for people
   (4) new technologies have increased acid rain

15 When receiving x rays, individuals wear a lead
   shield over major organs in order to limit the
   body’s exposure to radiation. One reason for this
   procedure is to
   (1) protect the patient against broken bones
   (2) prevent mutations in gametes
   (3) improve circulation in the patient
   (4) increase the chance of a change in DNA
