• Which of these is a characteristic of body cells
  that require large amounts of energy?
• A They have a large number of mitochondria.
• B They have a supplementary Y chromosome.
• C They have a two-layer membrane.
• D They have a storage area for albumin proteins.

3

• Because chewing begins the breakdown of food
  before it is swallowed, digestion starts in the
  mouth and throat. Which of the following systems
  aids most in this early stage of digestion?
• A Immune system
• B Excretory system
• C Muscular system
• D Respiratory system

4

• Unlike other animals, mammals can perspire. The
  main benefit of perspiring is that it
• A removes extra water from the cells
• B cools the skin with evaporation
• C removes dirt from the surface of the skin
• D relaxes the muscles

5

• When viewing a prepared slide under the compound
  microscope, a student has to remove his glasses.
  This means he will need to readjust for fine
  focus with which part labeled above?
• A 1
• B 2
• C 3
• D 4

6

• Compared to a skin cell, a muscle cell is likely
  to have more
• A Golgi bodies
• B mitochondria
• C cell membranes
• D chloroplasts

7

• A cell with numerous ribosomes is probably
  specialized for

• C cell division
• D protein synthesis

8

• Which of the following organelles is present in
  both prokaryotes and eukaryotes?

9

• In the cell membrane model shown below, the
  molecules which move large molecules into and out
  of the cell are known as

10

• An important difference between viruses and
  living cells is that viruses
• A cannot reproduce outside of cells
• B contain more nuclei than cells
• C cannot mutate but cells can
• D need an energy source but cells do not

11

• The cell membrane of the red blood cell will
  allow water, oxygen, carbon dioxide,and glucose
  to pass through. Because other substances are
  blocked from entering, this membrane is called
• A perforated.
• B semi-permeable.
• C non-conductive.
• D permeable.

12

• Eukaryotic cells are differentiated from
  prokaryotic cells because eukaryotic cells
• A are much smaller.
• B have permeable membranes.
• C have a higher rate of reproduction.
• D have nuclei.

13

• Which cellular organelle is responsible for
  packaging the proteins that the cell secretes?
• A cytoskeleton
• B cell membrane
• C lysosome
• D Golgi apparatus

14

• In order for the body to maintain homeostasis,
  the chemical decomposition of food to produce
  energy must be followed by
• A water intake.
• B muscle contractions.
• C waste removal.
• D nervous impulses.

15

• Carbon dioxide is produced as cells break down
  nutrients for energy. Which of the following
  pairs of systems would participate in removing
  the carbon dioxide from the body?
• A endocrine and circulatory
• B circulatory and respiratory
• C respiratory and endocrine
• D reproductive and excretory

16

• Which of the following require a host cell
  because they are not able to make proteins on
  their own?
• A blue-green algae
• B bacteria
• C protozoans
• D viruses

17

• Viruses are exceptions to the cell theory, but
  they have some characteristics of living things.
  What is one of these characteristics?
• A They are made up of many specialized cells.
• B They contain genetic material.
• C They reproduce by mitosis.
• D They contain chlorophyll.

18

• Which structure includes all of the others?
• A nucleolus
• B nucleus
• C chromosomes
• D genes

19

• Most cell membranes are composed principally of
• A DNA and ATP
• B proteins and lipids
• C chitin and starch
• D nucleotides and amino acids

20

• Sodium ions are "pumped" from a region of lower
  concentration to a region of higher concentration
  in the nerve cells of humans. This process is an
  example of
• A diffusion
• B passive transport
• C osmosis
• D active transport

21

• Which activity is illustrated in the diagram of
  an ameba shown below? 
• A endocytosis
• B synthesis
• C exocytosis
• D osmosis

22

• During a race, the body temperature of a runner
  increases. The runner responds by perspiring,
  which lowers body temperature. This process is an
  example of
• A maintenance of homeostasis
• B an antigen-antibody reaction
• C an acquired characteristic
• D environmental factors affecting phenotype

23

• The diagram below represents a group of organs in
  the human body. Urine leaves the urinary bladder
  by passing through structure 
• A
• B
• C
• D

24

• The diagram below shows the same type of molecule
  in area A and area B. With the passage of time,
  some molecules move from area A to area B. This
  movement is the result of the process of 
• A phagocytosis
• B pinocytosis
• C diffusion
• D cyclosis

25

• Which structure is best observed using a compound
  light microscope?
• A a cell
• B a virus
