Unit 1- Biol 230 Athabasca EXAM
|\ |\ |\ |\ |\ |\
QUESTIONS WITH ANSWERS |\ |\
Integration: - CORRECT ANSWERS ✔✔The process in |\ |\ |\ |\ |\ |\ |\
which the bodies systems work together to accomplish a
|\ |\ |\ |\ |\ |\ |\ |\ |\
unified/common task |\
emergent properties - CORRECT ANSWERS ✔✔In a
|\ |\ |\ |\ |\ |\ |\
complex hierarchy such as the body's organizational plan,
|\ |\ |\ |\ |\ |\ |\
as
|\
each level gives rise to the next highest level, new
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
properties emerge |\
that are not present at the levels below
|\ |\ |\ |\ |\ |\ |\
Metabolism: - CORRECT ANSWERS ✔✔The sum of all the |\ |\ |\ |\ |\ |\ |\ |\ |\
chemical reactions that occur in the body (catabolism
|\ |\ |\ |\ |\ |\ |\
"breakdown" eg fat breakdown by the gall bladder,
|\ |\ |\ |\ |\ |\ |\ |\ |\
anabolism "build up" eg amino acids |\ |\ |\ |\ |\
Responsiveness: - CORRECT ANSWERS ✔✔: Is the bodies |\ |\ |\ |\ |\ |\ |\ |\
ability to detect and respond to changes. Eg the body
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
regulates body temperature, which Is why you shiver
|\ |\ |\ |\ |\ |\ |\ |\
when you get cold (Internal). External factor would be
|\ |\ |\ |\ |\ |\ |\ |\ |\
protecting your face when you see a ball coming at you
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
(external)
,Movement: - CORRECT ANSWERS ✔✔Includes motion of |\ |\ |\ |\ |\ |\ |\
the whole body, organs, single cells, and tiny structures
|\ |\ |\ |\ |\ |\ |\ |\ |\
inside of cell |\ |\
Growth: - CORRECT ANSWERS ✔✔Is an increase in body
|\ |\ |\ |\ |\ |\ |\ |\ |\
size that results from an increase in the size of existing
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
cells, an increase in the number of cells or both.
|\ |\ |\ |\ |\ |\ |\ |\ |\
Differentiation: - CORRECT ANSWERS ✔✔Is the |\ |\ |\ |\ |\ |\
development of a cell from an unspecialized to a |\ |\ |\ |\ |\ |\ |\ |\ |\
specialized state. Each type of cell in the body has a |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
specialized structure and function that differs from that of |\ |\ |\ |\ |\ |\ |\ |\
its precursor (ancestor) cells. For example, erythrocytes
|\ |\ |\ |\ |\ |\ |\ |\
(red blood cells) and several types of leukocytes all arise
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
from the same unspecialized precursor cells in bone
|\ |\ |\ |\ |\ |\ |\ |\
marrow.
Stem cells : - CORRECT ANSWERS ✔✔Precursor cells that
|\ |\ |\ |\ |\ |\ |\ |\ |\
can divide and give rise to cells that undergo
|\ |\ |\ |\ |\ |\ |\ |\ |\
differentiation.
Reproduction: - CORRECT ANSWERS ✔✔Refers to the |\ |\ |\ |\ |\ |\ |\
formation of new cells for tissue growth, repair, or
|\ |\ |\ |\ |\ |\ |\ |\ |\
replacement. Or the production of a new individual |\ |\ |\ |\ |\ |\ |\
,Homeostasis - CORRECT ANSWERS ✔✔The maintenance |\ |\ |\ |\ |\ |\
of relatively stable conditions in the body's internal
|\ |\ |\ |\ |\ |\ |\ |\
environment
Intracellular fluid: - CORRECT ANSWERS ✔✔The fluid |\ |\ |\ |\ |\ |\ |\
within cells compromises 2/3 of total body fluid
|\ |\ |\ |\ |\ |\ |\
Extracellular fluid: - CORRECT ANSWERS ✔✔The fluid that |\ |\ |\ |\ |\ |\ |\ |\
is outside of the cells which compromises the other 1/3 of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the body and is composed 80% intercellular fluid
|\ |\ |\ |\ |\ |\ |\ |\
(inbetween cells) and 20 % plasma |\ |\ |\ |\ |\
Interstitial fluid: - CORRECT ANSWERS ✔✔The fluid the
|\ |\ |\ |\ |\ |\ |\ |\
fills the narrow spaces between the cells
|\ |\ |\ |\ |\ |\
Plasma: - CORRECT ANSWERS ✔✔The fluid portion of
|\ |\ |\ |\ |\ |\ |\ |\
blood
Homeostasis: - CORRECT ANSWERS ✔✔The maintenance |\ |\ |\ |\ |\ |\
of relatively stable conditions in the body's internal
|\ |\ |\ |\ |\ |\ |\ |\
environment
Steady state: - CORRECT ANSWERS ✔✔energy is needed
|\ |\ |\ |\ |\ |\ |\ |\
to keep the regulated parameter at a relatively constant
|\ |\ |\ |\ |\ |\ |\ |\ |\
level
, Equilibrium: - CORRECT ANSWERS ✔✔conditions remain |\ |\ |\ |\ |\ |\
constant without the expenditure of energy
|\ |\ |\ |\ |\
Feedback system - CORRECT ANSWERS ✔✔: is a cycle of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
events in which a parameter of the internal environment
|\ |\ |\ |\ |\ |\ |\ |\ |\
is monitored, evaluated,changed, remonitored,
|\ |\ |\ |\
reevaluated, and so on. |\ |\ |\
Stimulus: - CORRECT ANSWERS ✔✔Any disruption that
|\ |\ |\ |\ |\ |\ |\
changes a controlled variable is called a stimulus.
|\ |\ |\ |\ |\ |\ |\
Receptor: - CORRECT ANSWERS ✔✔: a body structure that
|\ |\ |\ |\ |\ |\ |\ |\
monitors changes in a controlled variable and sends
|\ |\ |\ |\ |\ |\ |\ |\ |\
input to a control center.
|\ |\ |\ |\
Negative feed back system: - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\
✔✔Reverses a change in a controlled variable |\ |\ |\ |\ |\ |\
Baroreceptors: - CORRECT ANSWERS ✔✔the receptors), |\ |\ |\ |\ |\ |\
pressure sensitive neurons located in the walls of certain
|\ |\ |\ |\ |\ |\ |\ |\ |\
blood vessels, detect the higher pressure. These neurons
|\ |\ |\ |\ |\ |\ |\ |\
send action potentials (input) to the brain (control center)
|\ |\ |\ |\ |\ |\ |\ |\
