Which of the following descriptions of the surface area of a maple-tree leaf best explains the relationship of structure to function?
A. The surface-area-to-volume ratio of the leaf is very low to
minimize loss of water.
B. The surface-area-to-volume ratio of the leaf is very low to
maximize photosynthesis.
C. The surface-area-to-volume ratio of the leaf is very high to
minimize waste elimination.
D. The surface-area-to-volume ratio of the leaf is very high to
maximize CO2 intake.

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
