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 - ANSWER-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.
E. all multicellular organisms are unicellular at some point in their life cycle. - ANSWER-C
When you are overheated, you perspire, and when you are too cold, you shiver to generate
heat. Which property of life is best represented by this example?
A. homeostasis
,2|Page
B. development
C. behavior
D. organization
E. adaptation - ANSWER-A
An isotonic solution means that the solute concentration outside the cell - ANSWER-Is the same
as inside the cell
In certain cancerous cells, the cell divides continuously even in the absence of a growth factor
(signaling molecule) that indicates the cell should divide. Which of the following could NOT
explain this?
( ) a receptor molecule that is always turned off
( ) a receptor molecule that is always activated
( ) a transduction pathway that is always turned on
( ) a target protein that is always activated
( ) a gene for cell division that is expressed when it should not be - ANSWER-a RECEPTOR
molecule that is always turned OFF
Plasma membrane - ANSWER-a phospholipid bilayer in which protein molecules are embedded.
surrounds plant and animal cells
glycolipids - ANSWER-lipids with carbohydrates attached to them; important for cellular
identification
Cytoplasm - ANSWER-a semifluid medium that contains organelles
,3|Page
glycoproteins - ANSWER-proteins with carbohydrates attached to them; important for cellular
identification
Radioactive isotopes are used to tag proteins in the cell membranes of mouse cells. These cells
are then fused with human cells in cultures. What is the likely consequence of the tagged
mouse proteins? - ANSWER-The tagged proteins DRIFT ACROSS cell membranes and are soon
found dispersed across both human and mouse cell membranes.
Which sequence of classification categories is in the proper order from least to most inclusive?
A. genus, class, kingdom, domain, order, phylum, species, family
B. domain, class, genus, family, species, order, phylum, kingdom
C. species, genus, family, order, class, phylum, kingdom, domain
D. genus species, order, class, family, kingdom, domain, phylum
E. species, genus, family, class, order, phylum, kingdom, domain – ANSWER-C
Surface-area-to-volume ratios indicate
A. cells must exceed a certain minimum size.
B. as cells get larger, their surface area actually decreases. C. that the largest cells have a less
proportionate need for food intake and waste removal.
D. a chicken egg is one cell thus demonstrating the upper limit for metabolizing cell size.
E. as cells get larger, their surface area gets larger but at a slower rate than the volume
increases. - ANSWER-E
Dead plants seen alongside a salted roadway died because the saline solution caused the cells
to - ANSWER-Undergo plasmolysis
Compared with a eukaryotic cell, a prokaryotic cell
A. lacks organelles beyond ribosomes.
, 4|Page
B. is larger.
C. does not require energy.
D. is not living.
E. has no method of movement. - ANSWER-A
E - ANSWER-Which classification category includes the most species?
A. family
B. genus
C. class
D. phylum
E. kingom
In the emergency room, saline solutions are often run into a person's vein. The saline solution
must be - ANSWER-0.9% NaCl
Which membrane transport process can continue whether the cell is alive or dead? - ANSWER-
diffusion
Cell wall - ANSWER-protects plant cells and is permeable
receptor proteins - ANSWER-membrane protein that is sensitive to the presences of specific
extracellular molecules like ligands - anything from an ion to a large complex molecule like a
hormone; binds to appropriate ligands and triggers a reaction in the cell
Macrophages, a typically white blood cell are able to remove bacteria from our bloodstream
and tissues by - ANSWER-Phagocytosis
