The aerobic threshold is the level of physical effort at which a person's cells are just beginning to carry
out fermentation to meet some of their energy
needs. Marathon runners try to stay at or below
the aerobic threshold so that they can go longer
distances without experiencing difficulty. While
running up and down the hills of San Francisco,
the runner was focused on trying to maintain the
pace he had when he was running on flat land.
What impact did this focus have on his ability to
maintain his aerobic threshold?

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.
