WCU PHYS 261 – midterm
QUESTIONS WITH CORRECT
ANSWERS
What is physiology? - correct answer ✔✔ the study of function of the body - how the body
parts work and carry out their life sustaining activities
Cell - correct answer ✔✔ The basic unit of structure and function in living things
Level of organization - correct answer ✔✔ atom, molecule, cell, tissue, organ, organ system,
organism, population of one species, eco system of diff species, biosphere
Homeostasis - correct answer ✔✔ a constant state of natural balance within the body
placebo effect - correct answer ✔✔ a positive result from a healing method due to a symbolic
or otherwise nonmaterial factor
nocebo effect - correct answer ✔✔ a negative placebo effect due to the expectation of adverse
consequences from receiving treatment
dependent variable - correct answer ✔✔ WHAT YOU MEASURE- ON Y AXIS
independent variable - correct answer ✔✔ variable that is manipulated
control group - correct answer ✔✔ the group that does not receive the experimental treatment.
,Atom - correct answer ✔✔ Basic unit of matter
3 subatomic particles - correct answer ✔✔ protons, neutrons, electrons
Protons - correct answer ✔✔ an atom that gains/loses protons becomes different element
Electron - correct answer ✔✔ becomes ion in same element
Neutron - correct answer ✔✔ becomes isotope of same element
atomic number - correct answer ✔✔ number on top
atomic mass - correct answer ✔✔ (at the bottom)Number of protons and neutrons
free radicals - correct answer ✔✔ unpaired electrons- normally pairs. will try to steal an
electron from another mol
covalent bond - correct answer ✔✔ a strong chemical bond resulting from the sharing of a pair
of electrons between two atoms
ionic bond - correct answer ✔✔ A chemical bond resulting from the attraction between
oppositely charged(cation and anions) ions
-opposites attract
