Biol 1201 Exam 1 LSU Questions with 100% Verified
Answers Latest Update
Question: Hypothesis
Answer:
a small statement that you can test
Question: 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
Question: Deductive
Answer:
Testing what you think is true; Design, Test, Conclusion
Question: Inductive
Answer:
making observations and solution from that observation; All observations have the same
result.
Question: 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)
Question: Atomic mass
Answer:
the atom's total mass, which can be approximated by the mass number
Question: Mass number
Answer:
the sum of protons and neutrons in the nucleus
Question: Atomic number
Answer:
the number of protons in an element
, Question: Isotopes
Answer:
two atoms of an element that differ in the number of neutrons
Question: Radioactive isotopes
Answer:
decay spontaneously, giving off particles and energy
Question: Hydrogen bonds
Answer:
forms when a hydrogen atom covalently bonded to one electronegative atom is also
attracted to another electronegative atom
Question: covalent bonds
Answer:
Strongest bonds in organisms are _______ ________ that form a cell's molecules.
Question:
Answer:
Question: Weak chemical bonds
Answer:
(ionic and hydrogen bonds) confer shape of large molecules and help molecules interact
Question: Chemical Equilibrium
Answer:
reached when the forward and reverse reaction rates are equal
Question: Van der Waals interactions
Answer:
attractions between molecules that are close together as a result of these charges
Question: Ionic bonds form between
Answer:
Metals and non metals
Question: Nonpolar covalent bond
