BIOLOGY 180 FINAL EXAM BYUI
EXPECTED QUESTIONS WITH VERIFIED ANSWERS
Question 1.
The longer the wavelength electromagnetic wave
ANSWER
the higher the energy of an False
Question 2.
Which of the following
ANSWER
elements has a valence of two? Oxygen and Sulfur
Question 3.
What type of bond valence electrons?
ANSWER
is formed by the equal sharing of A non-polar covalent bond
Question 4.
Polar molecules, such pate in which of the tions
ANSWER
as water, will commonly partici- Hydrogen bonding with following intermolecular interac-
polar molecules. Electrostatic interaction with ionic compounds.
Question 5.
Which of the following capability of forming
ANSWER
compounds would have the A molecule formed by poa hydrogen bond? lar covalent bonds.
Question 6.
What is the concentration ume of 300 mL containing (C12H22O11)?
ANSWER
of a solution with a vol- 8% 24 grams of sucrose
, Question 7.
A weak acid like acetic
ANSWER
acid: Will resist changes in pH so long as the pH is near the pKa.
Question 8.
Which of the following
ANSWER
are true regarding pKa? pKa is the negative logarithm of the Ka. pKa is the pH when the
conjugate base and weak acid are at the same concentration. pKa is physical characteristic of
each unique buffering system pH = pKa + log ([A-] / [HA])
Question 9.
A certain channel equally permeable tions are high on itive), while K+ concentrations of the cell

protein in the cell membrane is More Na+ ions will be to both Na+ and K+. Na+ concentra-
transported. the outside of the cell (which is pos- are high on the inside negative). Assuming
equal concen- both Na+ and K+, which of the is true regarding the movement this channel?
Question 10.
Which of the following electrochemical gradient against its concentration
ANSWER
types of transport can use the Secondary Active Transof sodium to move a solute port
gradient?
Question 11.
Which of the following energy from ATP hydrolysis?
ANSWER
membrane activities require Na+ ions moving out of the cell.
