BIO Beyond Study Guide Exam
Questions And Correct Answers.
What do you think that means about the interaction between phosphate and water? - 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? - 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? -
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. -
Answer A - Hydrophilic
B - Hydrophobic
C - Hydrophilic
Which molecules do you think come from and indicate the presence of life? - 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. - Answer Bond
Atom
During your explorations, what molecules did you find that make up the structural components of a cell?
- Answer Carbohydrates, Lipids, Proteins, Nucleic Acids
Which of the following would be a good definition of the atom according to Democritus? - Answer A
piece of something that is as small as possible
, What was JJ Thomson's biggest difference from Democritus' model? - Answer Atoms could be broken
down into
Which scenario below do you think is most likely for this experiment's results? Make a hypothesis. -
Answer 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! - Answer 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? - Answer Rutherford's model had a
small, dense, positive nucleus
What differences does Bohr's model have compared to Rutherford's? Select all that apply: - Answer
Distinct energy levels for electrons
Distinct orbits for electrons
How is Schrödinger's model different from Bohr's? - Answer Electrons don't have orbits but have
volumes they may occupy
Where is most of the mass in an atom located? - Answer Nucleus
What makes up most of the volume of an atom? - Answer Empty space
Bohr - Answer Electrons in orbits by energy levels
Rutherford - Answer Initial concept of nucleus
Thomson - Answer Initial concept of electrons
Schrödinger - Answer Electrons in clouds
