LSU Biol 1201 Exam 1 questions with answers
|\ |\ |\ |\ |\ |\ |\
Hypothesis - CORRECT ANSWERS ✔✔a small statement that you |\ |\ |\ |\ |\ |\ |\ |\ |\
can test
|\
Theory - CORRECT ANSWERS ✔✔broader in scope than a
|\ |\ |\ |\ |\ |\ |\ |\ |\
hypothesis and can lead to a new testable hypothesis; supported
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
by a large body of evidence in comparison to a hypothesis
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Deductive - CORRECT ANSWERS ✔✔Testing what you think is
|\ |\ |\ |\ |\ |\ |\ |\ |\
true; Design, Test, Conclusion
|\ |\ |\
Inductive - CORRECT ANSWERS ✔✔making observations and
|\ |\ |\ |\ |\ |\ |\
solution from that observation; All observations have the same
|\ |\ |\ |\ |\ |\ |\ |\ |\
result.
Valence - CORRECT ANSWERS ✔✔Outer shell of electrons; the
|\ |\ |\ |\ |\ |\ |\ |\ |\
number of unpaired electrons in the valence shell of an atom is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
generally equal to its valence (the # of covalent bonds it can
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
form)
Atomic mass - CORRECT ANSWERS ✔✔the atom's total mass,
|\ |\ |\ |\ |\ |\ |\ |\ |\
which can be approximated by the mass number
|\ |\ |\ |\ |\ |\ |\
Mass number - CORRECT ANSWERS ✔✔the sum of protons and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
neutrons in the nucleus |\ |\ |\
, Atomic number - CORRECT ANSWERS ✔✔the number of protons
|\ |\ |\ |\ |\ |\ |\ |\ |\
in an element
|\ |\
Isotopes - CORRECT ANSWERS ✔✔two atoms of an element that
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
differ in the number of neutrons
|\ |\ |\ |\ |\
Radioactive isotopes - CORRECT ANSWERS ✔✔decay |\ |\ |\ |\ |\ |\
spontaneously, giving off particles and energy |\ |\ |\ |\ |\
Hydrogen bonds - CORRECT ANSWERS ✔✔forms when a
|\ |\ |\ |\ |\ |\ |\ |\
hydrogen atom covalently bonded to one electronegative atom is
|\ |\ |\ |\ |\ |\ |\ |\
also attracted to another electronegative atom
|\ |\ |\ |\ |\ |\
covalent bonds - CORRECT ANSWERS ✔✔Strongest bonds in
|\ |\ |\ |\ |\ |\ |\ |\
organisms are _______ ________ that form a cell's molecules.
|\ |\ |\ |\ |\ |\ |\ |\
