LSU BIOL 1201 EXAM 1 QUESTIONS & DETAILED
C0MPLETE SOLUTIONS 100%
1. Hypothesis a small statement that you can test
2. Theory 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
3. Deductive Testing what you think is true; Design, Test, Conclusion
4. Inductive making observations and solution from that observation; All
ob- servations have the same result.
5. Valence 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)
6. Atomic mass the atom's total mass, which can be approximated by the
mass number
7. Mass number the sum of protons and neutrons in the nucleus
8. Atomic number the number of protons in an element
9. Isotopes two atoms of an element that ditter in the number of
neutrons
10. Radioactive isotopes decay spontaneously, giving ott particles and energy
11. Hydrogen bonds forms when a hydrogen atom covalently bonded to one
elec-
tronegative atom is also attracted to another
electronegative atom
12. covalent bonds Strongest bonds in organisms are that
form
a cell's molecules.
