BIOD 152 MODULE 1 COMPREHENSIVE EXAM
2026 FULL QUESTIONS AND CORRECT
ANSWERS ALREADY PASSED
◉ What is the appropriate term for a group of all the individuals that
can mate with each other living within a specified area?
Answer: population
◉ Which of the following is a prokaryotic domain?
Answer: Archaea
◉ A controlled experiment is one that _________ .
Answer: tests experimental and control groups in parallel
(Without a control factor, researchers have no basis for comparison
of their results and cannot determine what effect, if any, an
experimental factor may have)
◉ How is the information encoded in DNA actually used by
organisms?
Answer: The information in DNA is transcribed to RNA and then
translated into protein.
,◉ There are _________ naturally occurring elements.
Answer: 92
◉ How many electrons would be present in the valence shell of a
sulfur atom (atomic number 16, mass number 32)?
Answer: 6
(remember
atomic number=protons
in neutral atom protons=electrons
in sulfur there are 16 protons thus 16 electrons
to fill a valence shell; 1st shell needs 2 electrons, 2nd needs 8, 3rd
needs 16
so 2 electrons in 1st, 8 in 2nd, and finally remaining 6 in last shell
aka the valence shell)
◉ Which of the following is a trace element?
,-oxygen
-hydrogen
-copper
-carbon
-nitrogen
Answer: copper
(Trace elements are required in small amounts aka non essential
the essential elements in life are Carbon, Hydrogen, Oxygen, and
Nitrogen)
◉ Which of the following has negligible mass?
Element
Neutron
Atom
, Electron
Proton
Answer: electron
(A negligible mass is an amount of mass that is so small it can be
safely ignored during calculations
◉ The number of protons in an uncharged atom .
varies with the different isotopes
equals the number of electrons
equals the number of electrons in the outer orbital of the atom
equals the number of neutrons
determines its mass number
Answer: equals the number of electrons
(bc remember
in neutral atoms aka atoms with no charge protons will = the
number of electrons
