BIO 1201 GREGG EXAM 2 TEST PAPER
QUESTIONS AND SOLUTIONS VERIFIED 100
PERCENT CORRECT
⩥ 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.
