1.

1 Which observation could lead to the conclusion
  that an object is nonliving?
  (1) It passes on hereditary information only
      through asexual reproduction.
  (2) It carries out synthesis.
  (3) It cannot perform metabolic processes.
  (4) It is composed of a cell, but does not have
      tissues.

2 Decomposers are necessary in a food chain
  because they
  (1) manufacture food by photosynthesis
  (2) return nutrients to the ecosystem
  (3) absorb energy from the Sun
  (4) produce organic nutrients

3 In early spring, many wildflowers begin to grow,
  produce flowers, and release seeds. The leaves
  of the wildflowers make food before the leaves
  of the trees in the area begin to develop. The
  early growth pattern of the wildflowers would
  likely result in
  (1) decreased competition for sunlight between
      the trees and the wildflowers
  (2) decreased competition for suitable temperature
      between the trees and the wildflowers
  (3) increased competition for space between the
      trees and the wildflowers
  (4) increased competition for oxygen between
      the trees and the wildflowers

4 Which sequence best represents increasing
  complexity?
  (1) tissues → cells → organelles → organs
  (2) cells → organelles → organs → organism
  (3) organelles → cells → tissues → organs
  (4) organism → cells → tissues → organelles

5 The diagram below represents two processes that
  occur in organisms. A characteristic represented
  by X is common to both of these processes.

A characteristic that the two processes have in
common is that each process
(1) uses ATP              (3) uses oxygen
(2) requires enzymes      (4) moves molecules

6 The molecules represented in the diagram below
  can interact to cause a biochemical process to
  occur.

Molecule A and molecule B most likely represent
(1) a nerve signal and a gene
(2) a receptor and a hormone
(3) a chromosome and an antigen
(4) a starch and an amino acid

7 The cytoplasm in a single-celled organism and
  the circulatory system in a human both
  (1) break down molecules into smaller components
  (2) release energy to be used by the organism
  (3) transport substances throughout the organism
  (4) distribute blood to all of the parts of the
      organism

8 A hydrangea plant has blue flowers when grown
  in acidic soil, but has pink flowers when grown in
  basic soil. A clone of the pink-flowered plant is
  grown in acidic soil and produces blue flowers.
  This change in flower color is most likely due to
  (1) sexual reproduction in the plants, resulting
      in variation
  (2) asexual reproduction in the plants, resulting
      in variation
  (3) genes being expressed in different ways due
      to environmental conditions
  (4) a gene mutation that occurred after the clone
      was produced

9 The diagram below represents a microscopic
  structure observed during mitosis.

The region indicated by letter A is known as
(1) an enzyme            (3) a gene
(2) a gamete             (4) an amino acid

10 A significant difference between the effects of
   the genetic information passed on from asexually
   reproducing parents to their offspring and sexually
   reproducing parents to their offspring is the
   (1) degree of modification of the size of
       chromosomes
   (2) types of DNA subunits
   (3) number of chromosomes in the body cells of
       the offspring
   (4) amount of variation between the parents and
       the offspring

11 A normal sequence of DNA bases in a single
   human skin cell is CATGGC. If this sequence
   replicates in this cell and becomes GATGGC,
   this alteration will most likely be passed to
   (1) every cell that develops from it
   (2) all human body cells
   (3) offspring of the human
   (4) all skin cells of this person

12 Beta cells in the pancreas and human skin cells
   both contain the insulin gene. The beta cells can
   make insulin; however, skin cells cannot. Which
   process is responsible for this gene being
   expressed in one cell type and not in another
   cell type?
   (1) mitosis               (3) differentiation
   (2) replication           (4) meiosis

   expressed by a bacterial cell as a result of
   (1) sexual reproduction (3) genetic variability
   (2) random mutation       (4) genetic engineering

14 The photograph below shows a recently discovered
   all-black penguin chick and several typical blackand-white chicks.

The appearance of this penguin chick with all
black feathers might
(1) increase the types of foods penguins can eat
(2) decrease the diversity of the penguin
    population
(3) decrease the number of variations present in
    the black penguin population
(4) result in an increase in black penguins over
    time if the trait provides a reproductive
    advantage

   provide a scientific explanation for
   (1) the fossil record of ancient life-forms
   (2) predictions about the rate of global warming
   (3) the amount of precipitation in a rain forest
   (4) the amount of soil used to grow certain crops
