WCU PHYS 261 MOST ASKED QUESTIONS AND
100% CORRECT ANSWERS
What is physiology?
the study of function of the body - how the body parts work and carry out their life
sustaining activities
Cell
The basic unit of structure and function in living things
Level of organization
atom, molecule, cell, tissue, organ, organ system, organism, population of one
species, eco system of diff species, biosphere
Homeostasis
a constant state of natural balance within the body
placebo effect
a positive result from a healing method due to a symbolic or otherwise nonmaterial
factor
nocebo effect
a negative placebo effect due to the expectation of adverse consequences from
receiving treatment
dependent variable
WHAT YOU MEASURE- ON Y AXIS
independent variable
variable that is manipulated
control group
the group that does not receive the experimental treatment.
Atom
Basic unit of matter
3 subatomic particles
protons, neutrons, electrons
Protons
an atom that gains/loses protons becomes different element
, Electron
becomes ion in same element
Neutron
becomes isotope of same element
atomic number
number on top
atomic mass
(at the bottom)Number of protons and neutrons
free radicals
unpaired electrons- normally pairs. will try to steal an electron from another mol
covalent bond
a strong chemical bond resulting from the sharing of a pair of electrons between
two atoms
ionic bond
A chemical bond resulting from the attraction between oppositely charged(cation
and anions) ions
-opposites attract
Ions
positively and negatively charged atoms
(Na+ = lost one electron)
hydrogen bond
weak/partial
Flourine, Nitrogen, Oxygen
water surface tension, boiling, and freezing
van der Waals forces
weak, nonspecific forces between molecules.
CHO
most abundant
Carbon, Hydrogen, Oxygen
mono/disacch - simple sugar
poly- complex
Lipids
