• 1. (Concept/Process) Def/Ex
• 2. Sequence/Equation
• 3. Explanation
• 4. Result
• 5. Pairing
• 6. Proof/Just (Calc/Read/Infer)

5
Definition/Example

• 1 The transfer of genes from parents to their
  offspring is known as
• (1) differentiation (3) immunity
• (2) heredity (4) evolution
• 23 One biotic factor that affects consumers in an
  ocean ecosystem is
• (1) number of autotrophs
• (2) temperature variation
• (3) salt content
• (4) pH of water

6
Definition/Example

• 2 Which object forms by the contraction of a
  large sphere of gases causing the nuclear fusion
  of lighter elements into heavier elements?
• (1) comet (3) star
• (2) planet (4) moon
• 21 Which process requires water to gain heat
  energy from the environment?
• (1) evaporation (3) infiltration
• (2) condensation (4) precipitation

7
Sequence

• 14 Which sequence represents the correct order of
  processes that result in the formation and
  development of an embryo?
• (1) meiosis ? fertilization ? mitosis
• (2) mitosis ? fertilization ? meiosis
• (3) fertilization ? meiosis ? mitosis
• (4) fertilization ? mitosis ? meiosis

8
Sequence

• 30 According to the fossil record, which sequence
  correctly represents the evolution of life on
  Earth?
• (1) fish ? amphibians ? mammals ? soft-bodied
  organisms
• (2) fish ? soft-bodied organisms ? mammals ?
  amphibians
• (3) soft-bodied organisms ? amphibians ? fish ?
  mammals
• (4) soft-bodied organisms ? fish ? amphibians ?
  mammals

9
Explanation

• 21 All life depends on the availability of usable
  energy. This energy is released when
• (1) organisms convert solar energy into the
  chemical energy found in food molecules
• (2) respiration occurs in the cells of producers
  and high-energy molecules enter the atmosphere
• (3) cells carry out the process of respiration
• (4) animal cells synthesize starch and carbon
  dioxide

10
Explanation

• 43 Which statement best explains why location A
  has a cooler climate than location B?
• (1) Location A has a longer duration of
  insolation each day.
• (2) Location A is influenced by a cold ocean
  current.
• (3) Location B is farther from the equator.
• (4) Location B has less intense insolation each
  day.

11
Result

• 27 Increased industrialization will most likely
• (1) decrease available habitats
• (2) increase environmental carrying capacity for
  native species
• (3) increase the stability of ecosystems
• (4) decrease global warming

12
Result

• 42 Which event is caused by Earths revolution?
• (1) the apparent shift in the path of a Foucault
  pendulum
• (2) deflection of planetary winds to the right in
  the Northern Hemisphere
• (3) the apparent rising and setting of the Sun
• (4) different constellations observed in the
  night sky throughout the year

13
Pairing

• 2 Damage to which structure will most directly
  disrupt water balance within a single-celled
  organism?
• (1) ribosome (3) nucleus
• (2) cell membrane (4) chloroplast

• (2) progesterone and testosterone
• (3) estrogen and insulin
• (4) progesterone and estrogen

14
Pairing

• 11 When two tectonic plates collide, oceanic
  crust usually subducts beneath continental crust
  because oceanic crust is primarily composed of
  igneous rock that has
• (1) low density and is mafic
• (2) low density and is felsic
• (3) high density and is mafic
• (4) high density and is felsic

15
Proof - Justification

  results in a test to determine if drug A would be
  effective in treating cancer in white mice?
• (1) injecting 1 mL of drug A into 100 white mice
  with cancer
• (2) injecting 1 mL of drug A into 100 white mice
  with cancer and 0.5 mL of drug X into 100 white
  mice without cancer
• (3) injecting 1 mL of drug A into 100 white mice
  with cancer and 0.5 mL of drug X into another
  group of 100 white mice with cancer
• (4) injecting 1 mL of drug A into 100 white mice
  with cancer and 1 mL of distilled water into
  another group of 100 white mice with cancer

16
Proof-Justification

• 1 Evidence that the universe is expanding is best
  provided by the
