BIO 203 EXAM #1 QUESTIONS &
ANSWERS 100% SOLVED
Anatomy - ANSWERStructure of the body parts and how they relate to one another
Physiology - ANSWERFunction of the body's structural machinery. (Events
happening in the body on a cellular or molecular level)
Control Center - ANSWER"Brain" determines the set point/level of variation at which
the variable is to be maintained. It then analyzes the information it receives and then
determines the appropriate response or course of action
Efferent Pathway - ANSWEROutput of information sent from the control center to
effectors
Effectors - ANSWERMeans for the control centers response to the stimulus/what is
done to get back to homeostasis
Response - ANSWERthe effector feeds back to reduce the effect of stimulus and
returns variable to homeostatic level
Two Different Kind of Feed-Back Mechanisms - ANSWERPositive Feed-Back
Negative Feed-Back
Complementary of structure and function - ANSWERfunction always reflects
structure; what a structure can do depends on its specific form
Theory - ANSWERA hypothesis that has been tested with a significant amount of
data
Cell Theory - ANSWER(biology) the theory that cells form the fundamental structural
and functional units of all living organisms
Hypothesis - ANSWERA testable prediction, often implied by a theory
Palpatation - ANSWERthe act of feeling with the hand, placing two fingers on the
body to determing the condition of the underlying part
Phagocytosis - ANSWERA type of endocytosis in which a cell engulfs large particles
or whole cells
Integral Protein - ANSWERA transmembrane protein with hydrophobic regions that
extend into and often completely span the hydrophobic interior of the membrane and
, with hydrophilic regions in contact with the aqueous solution on one or both sides of
the membrane (or lining the channel in the case of a channel protein).
Peripheral Protein - ANSWERA protein loosely bound to the surface of a membrane
or to part of an integral protein and not embedded in the lipid bilayer.
Level of Structural Organization - ANSWERThe body as a hierarchy system in the
way its organized *goes from microscopic to macroscopic in scale*
Chemical Level - ANSWERAtoms are the tiniest building block of matter
Molecular Level - ANSWERMany atoms clamp together to form molecules
Cells - ANSWERSmallest unit of living matter that can maintain life and reproduce
Tissue - ANSWERGroup of similar cells that have a common function
4 basic tissue types - ANSWEREpithelial
Connective
Muscular
Nervous
Epithelial Tissue - ANSWERCovers body surfaces and lines body cavity
Connective Tissue - ANSWERSupports, protects and holds the body together
Muscular Tissue - ANSWERMovement specialized to contract or shorten to produce
movement
Organ - ANSWERa structure composed of two or more tissue types that performs a
specific function for the body
Nervous Tissue - ANSWERMeans of rapid internal communication by transmitting
electrical impulses
Organ System - ANSWEROrgans that work closely with one another to accomplish a
common purpose
Organismal Level - ANSWERHighest level or organization. The total of all structural
levels working in unison to promote life
*Humans have 11 organ systems*
Characteristics of life - ANSWERmovement
maintain boundaries
responsiveness/irritability
growth
metabolism
reproduction
digestion
excretion
