Interpreting Data
If cancer results from a single gene mutation in a somatic cell,
which of the following graphs would describe the incidence rate of
cancer as a function of age? Hint: The probability of mutation
leading to cancer would be constant and independent of age.

Biology and Society
This insufficiently developed human embryo was produced by inserting
a nucleus from an adult cell into a human egg cell—a potential clone.
The purpose was to develop embryonic stem cells. An embryonic stem
cell can potentially develop into any of the specialized cell
tissues/organs of an adult.
Despite its promise, do you think that therapeutic cloning is
ethically justifiable?

Biology and Society
Embryonic stem cells are currently derived from extra human blastocysts
that sometimes result from in vitro fertilization techniques. From 2001 to
2009, stem cell research supported by U.S. agencies was restricted to only
a small number of stem cell lines. (Meanwhile, other countries were going
ahead with embryonic stem cell research.) But in March 2009, President
Obama signed an executive order reversing federal opposition to
embryonic stem cell research.
Do you support the current U.S. governmental policy on stem cell
research?
Strongly
Agree
