Exam-biology 1108 exam 4(Chapter 33, 34, 35, 38)
Questions and Answers
As body size increases, what happens to the surface area/volume ratio and metabolic rates?
CORRECT ANS-Surface-area-to-volume ratios decline with cell size, so larger cells are
expected to use less energy per volume than smaller cells.
As body size decreases, what happens to the surface area/volume ratio and metabolic rates?
CORRECT ANS-a decrease in body size results in a higher metabolic rate.
What is Torpor? CORRECT ANS-decrease in activity and metabolism and allows animals to
survive adverse conditions.
Compare Hibernation to Estivation. CORRECT ANS-hibernation during the winter months,
in which case it enables them to maintain a reduced body temperature.
torpor in summer months with high temperatures and little water, it is called estivation.
List the four main tissue types in animal bodies? Examples? Functions? CORRECT ANS-
Epithelial tissue such as the skin or intestine lining, covers and lines organs and organ
cavities/tubes.
, Exam-biology 1108 exam 4(Chapter 33, 34, 35, 38)
Questions and Answers
Connective tissue such as loose connective tissue (fat, collagen/elastin) and dense connective
tissue, bind and support other tissues.
Muscle tissue such as skeletal, cardiac or smooth, provides movement if an organism and
materials within the organism.
Nervous tissue such as neurons and neuroglial cells, function as the senses and
interpret/respond to stimuli.
Where do epithelial tissues occur, and how are they named? CORRECT ANS-Epithelial
tissue covers and lines organs/cavities/tubes, and it is named by call shape and number of
layers.
How would you distinguish simple from stratified epithelium? CORRECT ANS-Simple is one
layer whereas stratified consists of several layers.

Questions and Answers
How would you distinguish squamous from cuboidal and columnar epithelium? CORRECT
ANS-Squamous looks flat like a fish scale. Cuboidal is short and fat, resembling a cube.
Columnar is tall and thin like columns.
simple squamous epithelium CORRECT ANS-Facilitated exchange of materials, gases and
nutrients diffuse easily
stratified squamous epithelium CORRECT ANS-Thick and protective, outermost layer of
human skin
cuboidal and columnar epithelium CORRECT ANS-secretion or absorption, have cilia or
microvilli
What type of tissue bonds and supports other tissue, consists of a few cells in a no cellular
matrix CORRECT ANS-Connective tissue
Supportive medium found outside of cells (liquids, proteins, minerals) CORRECT ANS-
Noncellular matrix

Questions and Answers
List and describe 6 types of connective tissue. Identify the cell type and matrix of each of
connective tissue example. Function of each type of tissue example? CORRECT ANS--
Adipose LC tissue contains adipocyte cells filled with lipid/fat; the cells swell to support each
other.
-Areolar LC tissue contains fibroblast cells in a protein matrix (collagen and elastin fibers).
-Dense connective tissue contains fibroblast cells in a protein matrix (collagen, elastin, and
reticulin).
-Blood connective tissue contains erythrocytes, leukocytes, and thrombocyte cells in a liquid
matrix (plasma).
-Cartilage connective tissue contains chondrocyte cells in a lacuna in a protein matrix (solid
collagen).
-Bone connective tissue contains cells in a lacuna within a mineral matrix (CaPO3).
List and explain the similarities and differences among the three type of muscle tissue.
CORRECT ANS-Muscle tissue allows movement of an organism and materials within that
organism; consist of elongated cells (muscle fibers).
