BIO 110 TUTORIAL 1 AND 2 QUESTIONS
AND ANSWERS
biology - Correct Answers -study of life
biological evolution - Correct Answers -changes in a genetic structure of a population
adaptions - Correct Answers -traits that help an organism survive in it current enviro
natural selection - Correct Answers -process which pop. becomes better adapted to its
enviro. over time
differential reproduction - Correct Answers -best adopted ones more likely to reproduce
than less adapted
what drives evolution? - Correct Answers -changing enviro
life - Correct Answers -condition distinguishing living organisms and nonliving matter
The Evolution Canyons are comprised of two mountain slopes - the "African" slope and
the "European slope". What is a reasonable hypothesis about the mice living on these
slopes? - Correct Answers -Mice living on the "African" slope are hypothesized to have
lighter coat color than the mice living on the "European" slope.
Biology is the study of life - but there is no simple definition of life. How do we recognize
living things from non-living things? - Correct Answers -We recognize living things by
their shared features such as energy transformation or reproduction.
How is biological evolution defined most succinctly? - Correct Answers -Changes in the
genetic structure of a population over time.
Many of the properties of water, including cohesion, the lower density of ice when
compared to liquid water, and its high heat of vaporization all are a result of the: -
Correct Answers -hydrogen bonds that form between water molecules.
2. Why is water a polar molecule? - Correct Answers -Because the oxygen atom is
more electronegative than the hydrogen atoms.
Water is essential to life but water is not an organic molecule. Why? - Correct Answers -
Organic molecules contain carbon and water does not contain carbon.
