Assume a group of scientists has managed to set up an experiment simulating
the conditions of early Earth that resulted in a cell with DNA using RNA to
produce proteins from amino acids as modern cells do. What conclusion could
they draw from this experiment? - ANS ✓It is possible for a cell similar to a
modern cell to form under the conditions of the experiment.
A variety of organic molecules have been found in meteorites that have landed
on Earth, including individual amino acids and lipid molecules. To date,
however, no microspheres have been found on these meteorites. Why is it
unlikely that microspheres will ever be found on a meteorite even though
lipids can form in them? - ANS ✓Groups of lipids will only form into microspheres
when they are in liquid water
Which of the following best compares the structures of lipids and
carbohydrates? - ANS ✓Both consist of carbon, hydrogen, and oxygen, but
carbohydrates have repeating structural unit and lipids do not.

Which of the following best describes the difference between the functions of
nucleic acids and enzymes? - ANS ✓Nucleic acids contain the genetic code for
protein synthesis, while enzymes catalyze chemical reactions.
Some proteins catalyze biochemical reactions. If a genetic defect prevented a
protein catalyst from being produced, which of the following do you predict
would happen in the cell? - ANS ✓The reaction the protein catalyzes would
proceed very slowly if not at all.
Which of the following best summarizes why the technological invention of
microscopes was important to biology? - ANS ✓It allowed for development of the
cell theory.
Early elements of the cell theory followed soon after the development of
Hooke's light microscope. What does this relationship suggest about the
evolution of the cell theory since Hooke? - ANS ✓Improvements in technology
are closely related to changes in the cell theory.
Which of the following characteristics defines a cell as a eukaryote? - ANS
✓Having a nucleus
