2 Forests, mountains, rivers, and marshes are
  examples of the wide variety of ecosystems in
  New York State. The diversity of these ecosystems is most likely the result of
  (1) the variety of abiotic conditions in these
      regions
  (2) interactions between producers and
      decomposers
  (3) increased efforts to protect endangered
      species
  (4) a lack of competition between the heterotrophs living there

3 The diagram below represents two organisms.

Which statement concerning organism A and
organism B is correct?
(1) Organism A contains organs, whereas
    organism B lacks organs.
(2) Organism A and organism B have the same
    organ systems.
(3) Organism A and organism B both have
    structures that perform life processes.
(4) Organism A lacks structures that help
    maintain dynamic equilibrium.

4 Which statement best describes the organelles
  in a cell?
  (1) All organelles are involved directly with
      communication between cells.
  (2) Organelles must work together and their
      activities must be coordinated.
  (3) Organelles function only when there is a disruption in homeostasis.
  (4) Each organelle must function independently
      of the others in order to maintain homeostasis.

  are directly used when a human runs.
              circulatory system
               muscular system
                skeletal system
  Which system should also be included in the list?

7 In a pine forest, there are different species of
  birds known as warblers that are able to coexist
  on the same pine trees. The Cape May warblers
  feed on insects located on the tips of the highest
  pine branches. The yellow-rumped warblers
  feed on insects on lower branches of the same
  trees. The different feeding locations for these
  two species of warblers indicate that they have
  different
  (1) niches
  (2) ecosystems
  (3) methods of asexual reproduction
  (4) methods of selective breeding

8 The diagram below represents the locations of
  two mutations in a strand of a DNA molecule.

If this DNA is located in the nucleus of a skin
cell, the cell will
(1) pass the mutations on to only half the cells
    that develop from it
(2) delete all of the DNA in the nucleus and
    synthesize new DNA
(3) correct the mutations after several generations
(4) pass the mutations on to the cells that
    develop from it

9 A human skin cell contains 46 chromosomes. A
  frog sperm cell contains 12 chromosomes.
  Which pair of numbers shows the chromosome
  number of a normal gamete from each of these
  species?
  (1) human 46; frog 12 (3) human 23; frog 24
  (2) human 46; frog 24 (4) human 23; frog 12

10 According to the theory of biological evolution,
   most present-day species of organisms
   (1) developed from similar, smaller prehistoric
       organisms
   (2) have always existed in the form they have
       today
   (3) developed from fossils of the other organisms
   (4) descended from earlier, different species of
       organisms

11 Corn seeds with identical genetic information
   were planted on two adjacent farms. The corn
   plants on one farm were well fertilized and grew
   large, while the plants on the other farm were
   not given fertilizer and did not grow as large.
   The best explanation for these observations is
   that
   (1) crops grow differently in different climates
   (2) the corn plants all contained mutated genes
       that made them grow
   (3) environmental conditions affect gene
       expression
   (4) the plants on one farm had different genes
       from the plants on the other farm

12 The male red-winged blackbird defends its
   territory and uses loud vocalizations to attract a
   mate. Such behavior directly benefits these birds
   because it results in
   (1) increased competition for food
   (2) greater reproductive success
   (3) reduced biodiversity
   (4) global stability

13 Extinction occurs when the environment
   changes and
   (1) a species can reproduce successfully
   (2) an individual has adaptive characteristics
       insufficient to allow survival
   (3) all members of a species are no longer living
   (4) one individual produces some offspring that
       evolve into a new species

   development, and eventual reproduction of
   sexually reproducing organisms is present in
   (1) sperm cells, only
   (2) egg cells, only
