LSU BIO 1201 ACTUAL EXAM 2026 QUESTIONS
WITH ANSWERS GRADED A+
◉ Theory. Answer: 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. Answer: Testing what you think is true; Design, Test,
Conclusion
◉ Inductive. Answer: making observations and solution from that
observation; All observations have the same result.
◉ Valence. Answer: 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. Answer: the atom's total mass, which can be
approximated by the mass number
, ◉ Mass number. Answer: the sum of protons and neutrons in the
nucleus
◉ Atomic number. Answer: the number of protons in an element
◉ Isotopes. Answer: two atoms of an element that differ in the number
of neutrons
◉ Radioactive isotopes. Answer: decay spontaneously, giving off
particles and energy
◉ Hydrogen bonds. Answer: forms when a hydrogen atom covalently
bonded to one electronegative atom is also attracted to another
electronegative atom
◉ covalent bonds. Answer: Strongest bonds in organisms are _______
________ that form a cell's molecules.
◉ Weak chemical bonds. Answer: (ionic and hydrogen bonds) confer
shape of large molecules and help molecules interact
◉ Chemical Equilibrium. Answer: reached when the forward and
reverse reaction rates are equal
