What two components are commonly found in the extracellular matrix that help resist
stretching and provide resilience?
( ) proteins & polysaccharides
( ) proteins & phospholipids
( ) polysaccharides & phospholipids
( ) amino acids & phospholipids
( ) nucleic acids & proteins - Correct Ans✓✓ PROteins & POLYsaccharides
A cell placed in a hypotonic solution will - Correct Ans✓✓ Gain water
2. According to cell theory
A. all organisms are composed of tissues.
B. the smallest unit of life is a nucleus.
C. animals but not plants are composed of cells.
D. a multicellular organism is composed of many cells.
E. new cells arise only from preexisting cells. - Correct Ans✓✓ E
C - Correct Ans✓✓ Which level of biological organization is composed of tissues?
A. organism
B. organ system
C. organ
D. cell
E. molecules
A differentially permeable membrane separates a molasses solution from distilled water. With
time, the - Correct Ans✓✓ Molasses will become more diluted

Which function does the lipid bilayer component of the plasma membrane NOT provide
for the cell?
( ) defines a permeable boundary between the organized interior and the chaotic external
environment
( ) provides an impermeable, self-sealing membrane that keeps all internal living processes
sealed inside
( ) controls the exchange of molecules between one cell and adjacent cells or the environment
( ) provides a fluid and flexible boundary that insulates the interior from the variations in
humidity, food, and other external conditions
( ) provides a matrix for proteins that regulate the exchange of molecules between the inside
and outside of the cell - Correct Ans✓✓ provides an impermeable, self-sealing membrane
that keeps all internal living processes sealed inside
Cell theory - Correct Ans✓✓
1) all organisms are composed of one or more cells
2) cells are the basic living unit of structure and function in organisms
3) all cells come only from other cells
fluid mosaic model - Correct Ans✓✓ membrane is not rigid, it is flexible and changes shape
Eukaryotic cells - Correct Ans✓✓ cells that have a nucleus
makes it possible to distribute molecules in membrane, slight damage can be repaired, allows
membranes to fuse together - Correct Ans✓✓ 3 reasons fluidity is important
The cell membrane is composed of - Correct Ans✓✓ lipids and proteins.
A membrane sac filled with large molecules of oil is suspended in a beaker of water. What
will happen? - Correct Ans✓✓ Water will enter the sac and it will swell

E - Correct Ans✓✓ Which sequence correctly lists the different levels of biological
organization, from the smallest and simplest to the largest and most complex?
A. cells-organs-tissues-organ systems-organism
B. cells-tissues-organ systems-organs-organism
C. tissues-cells-organs-organ systems-organism
D. tissues-organs-organ systems-organsims-cells
E. cells-tissues-organs-organ systems-organisms
3. The body of a slime mold that flows over a rotten log appears to lack any partitioning
into distinct cells; however it does become cellular when it changes form and produces
spores. The surfaces of parasitic flatworms and some insect tissues are "syncytial"
layers of living material that developed from a single cell but now contains many nuclei
but lack partitioning by cell membranes. These tissues actively consume food and
produce wastes. Considering that the cell theory states that "all living things are
composed of cells," then
A. these tissues are not living because they violate the cell theory.
B. this proves some vital force is involved beyond normal cell structures in order to give life
to living organisms.
C. these tissues are obviously a bridge between nonliving and primitive living cells.
D. the general concept of life-is-cellular still holds since sometime in their life these
organisms still utilize - Correct Ans✓✓ D
4. The cell theory states
A. all organisms are composed of only one cell.
B. organelles are the basic living unit of structure and function of organisms.
C. all cells come only from other cells.
D. all organisms are composed of only one cell AND organelles are the basic living unit of
structure and function of organisms.
