molecule can be used for the generation of energy?
- Carbohydrates
6. Microtubules, actin, and intermediate filaments are all found in cells. They are
responsible for a number of activities. Which of the following is not an activity
performed by those three materials?
- Microtubules: support, cell division (separation of chromosomes), cell/organelle
movement
- Actin: Forms microfilaments, cell movement, signaling, muscle contraction, cell
junctions
- Intermediate Filaments: support
7. All cells possess this structure that isolates them from the environment:
- Plasma membrane
- Phospholipid bilayer
,8. Considering all the properties that are used to define life, which of the following is not
one of the properties?
- Life is Isolated
- Has to be a barrier that separates it from its environment
- Life is Complex and Ordered
- Life is not at equilibrium
- Life at equilibrium is dead
- Life is regulated
- Life is responsive
- Life grows and reproduces
- Life is well adapted (this is subjective)
- Life requires and uses energy
- Life carries instructions DNA/RNA produces the instructions for things life needs for the
living thing to do all of the above
9. (A = True / B = False) The inherent difficulty of studying biology, is that each part of the
hierarchy from cells to ecosystems is entirely different in structure and themes.
- False

ancestor, we would see something interesting and that is:
- An early prokaryotic cell as the precursor to all cells
11. (A = True / B = False) The concept of evolution is still under debate in the scientific
community, this demonstrates that all topics in science are open for discussion!
- False
12. In 1953, Miller tested a hypothesis exploring the idea of the “primordial conditions” of
Earth. During this experiment in which he created a “sea” and an “atmosphere” he
electrified the atmosphere to simulate lightning as a result what was created?
- Organic molecules

- Exploding stars
15. Which of the following statements about atoms is true?
- Definition of an atom
16. What is an ion?

- Carbon
22. Which molecule, listed below, shows polar bonds?
-
23. (A = True / B = False) Ionic bonds are similar to electrostatic interactions, but they differ
in that electrostatic interactions are created by the transfer of electrons from one atom to
another.
