HELPPP!! WHAT IS THE CONTROL GROUP?? IS THERE EVEN ONE?? You are trying to determine whether plants grow better in natural light or artificial light. You test your problem by placing 2 plants in
artificial light and 2 plants in natural light. You measure their length each day for two weeks. What is the control for your experiment?

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.
