Biophysics Final Exam || with A+ Guaranteed Solutions.
Force correct answers That which causes or tends to cause a change in a body's motion or shape.
Strength correct answers The ability of a muscle or group of muscles to exert force against a
resistance.
Velocity correct answers The speed and direction of a body.
Power correct answers The product of an applied force and the speed with which it is applied;
the quantity of work done per unit time.
Kinesiology correct answers The study of human movement from an anatomical and/or
mechanical perspective. (Podcast)
Kinetics correct answers An area of study that is concerned with the forces that act on a system.
(Podcast)
Mobility correct answers The ease with which an articulation or a series of articulations is
allowed to move before being restricted by the surrounding structures.
Inertia correct answers The resistance of a body to a change in its state of motion.
A body in motion will remain in motion; a body at rest will remain at rest. (Podcast)
Acceleration correct answers The change in velocity (speed and/or direction) per unit of time.
Biomechanics correct answers The area of study wherein knowledge and methods of mechanics
are applied to the structure and function of the living human system. (Podcast)
Center of Gravity (CG) correct answers That point at which all the body's mass seems to be
concentrated; the center of mass.
Synergy correct answers The cooperative effort of two or more muscles contracting to
accomplish a single movement.
Mass correct answers The measure of a body's inertia; the amount of matter in a body.
Kinetic Friction correct answers The friction that exists between two surfaces sliding past each
other. (Podcast)
Density correct answers The mass per unit volume of an object or body (mass density); or weight
per unit volume (weight density).
D=M/V
, Volume correct answers The three-dimensional space occupied by a body (length, width and
height).
Weight correct answers The force of earth's gravitational attraction on a body's mass.
Speed correct answers The magnitude of a body's displacement per unit of time without regard to
direction.
RxT=D
Work correct answers The force applied to a body multiplied by the distance though which that
force is applied.
W=FxD
Sublimation correct answers Changing from solid to gas without becoming liquid first (e.g., dry
ice).
Metabolic Rate correct answers The sum total of the energy turnover of a cell. (Podcast -
Biology of Heat)
Acclimatization correct answers The process of physiological and biochemical changes an
animal undergoes in response to seasonal changes in climate. (Podcast - Biology of Heat)
Metabolic Compensation correct answers Adjustment of biochemical machinery to changes in
temperature. (Podcast - Biology of Heat)
Homeotherm correct answers An organism that regulates its body temperature at a constant level.
(Podcast - Biology of Heat)
Poikilotherm correct answers An organism whose temperature changes. (Podcast - Biology of
Heat)
Heterotherm correct answers An organism that regulates its body temperature some of the time
(e.g., hibernation). (Podcast - Biology of Heat)
Ectotherm correct answers An organism that depends largely on external sources of heat to
maintain body temperature above the environmental temperature (e.g., lizards). (Podcast -
Biology of Heat)
Endotherm correct answers An organism that regulates body temperature by producing heat
through metabolic pathways (e.g., mammals, birds). (Podcast - Biology of Heat)
Transfer of Heat correct answers 1. Conduction
2. Convection
3. Radiation
