BIO Beyond Exam Questions &
Answers (Grade A+)
What do you think that means about the interaction between
phosphate and water? -
correct answer ✅Water and the head of a phospholipid attract
each other like magnets, so they interact well.
Do you think they would be polar like the phosphorous group? -
correct answer ✅The tail will not be polar like the phosphorous
group.
Do you think they would interact with water as well as, better than,
or less than the head group? -
correct answer ✅The tail end will interact with water less than the
head group.
Consider again the diagram of the cell membrane. It divides into
three regions, kind of like a sandwich. Label the regions as
hydrophilic (water-loving) or hydrophobic (water-hating) in the
diagram below. -
correct answer ✅A - Hydrophilic
B - Hydrophobic
C - Hydrophilic

Answers (Grade A+)
Which molecules do you think come from and indicate the
presence of life? -
correct answer ✅water, organelles, nucleotides, monosaccarides
Shown to the right are diagrams of each of the components you
identified in your exploration. They, in turn, are made up of smaller
pieces called atoms, connected by things called bonds. Identify in
the graphic below which pieces you think are atoms and which you
think are bonds. -
correct answer ✅Bond
Atom
During your explorations, what molecules did you find that make up
the structural components of a cell? -
correct answer ✅Carbohydrates, Lipids, Proteins, Nucleic Acids
Which of the following would be a good definition of the atom
according to Democritus? -
correct answer ✅A piece of something that is as small as possible
What was JJ Thomson's biggest difference from Democritus'
model? -
