BIO Beyond Exam Questions with Correct
Answers
What do you think that means about the interaction between phosphate and water?
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?
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?
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.
A - Hydrophilic
B - Hydrophobic
C - Hydrophilic
Which molecules do you think come from and indicate the presence of life?
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.
, Bond
Atom
During your explorations, what molecules did you find that make up the structural
components of a cell?
Carbohydrates, Lipids, Proteins, Nucleic Acids
Which of the following would be a good definition of the atom according to Democritus?
A piece of something that is as small as possible
What was JJ Thomson's biggest difference from Democritus' model?
Atoms could be broken down into
Which scenario below do you think is most likely for this experiment's results? Make a
hypothesis.
the beam of alpha particles will pass through mostly unchanged and some will bounce back
Rutherford saw to his surprise that most particles went through the foil but some were
deflected and even bounced back!
Thomson's model of the atom had a diffuse positive charge, so the particles should not have
been deflected very far
How was Rutherford's model different from his mentor, Thomson's?
Rutherford's model had a small, dense, positive nucleus
What differences does Bohr’s model have compared to Rutherford’s? Select all that
