BS 161 Exam 1 questions with verified answers
Bond Ans✓✓✓ Interactions between atoms
cellulose function Ans✓✓✓ provides structure to plant cell walls
Claim + since/because (Linking statement): Ans✓✓✓ A sentence that clearly
states the claim or answer to the question, and uses since or because to link to a
summary of the relevant observations and reasoning previously stated.
collagen or prion function Ans✓✓✓ Collagen provides structural support: porin
allows substances to cross membranes
Complete the sentence to describe the relationship between bond formation and
entropy (disorder): when a bond forms Ans✓✓✓ entropy increases
DNA function Ans✓✓✓ stores genetic information
Effect on membrane fluidity of saturated fatty acid Ans✓✓✓ Phospholipids can
pack very tightly together, less fluid, solid at room temperature
effects on membrane fluidity Ans✓✓✓ more fluid since there is less LDFS
electronegativity Ans✓✓✓ ability for atoms to attract electrons.
, Evidence / observations: Ans✓✓✓ observations through the experiment,
something like number data, quantitative, graphs, chemical sutures( what you use
to support the claim)
example macromolecule of a carb Ans✓✓✓ cellulose
example macromolecule of a nucleic acid Ans✓✓✓ DNA
example macromolecule of a protein Ans✓✓✓ collagen or porin
how cellulose function is supported Ans✓✓✓ Cellulose molecules pack together
denestly to form rigid support structures
how collagen or prion in supported Ans✓✓✓ Long parallel fibers of collagen give
strength and elasticity:
porin has pore to allow substances to cross
how DNA is supported? Ans✓✓✓ The strong covalent bonds between
nucleotides preserve the specific sequence
Hydrogen Bond interactions Ans✓✓✓ An interactions between a hydrodrogen
with a permanent particle charge and a more electronegative atom.
Hydrophobic clustering Ans✓✓✓ The tendency of hydrophobic molecules to
group together in the presence of water.
