Why can mutations in the dna of a single cell affect the function of an entire organism?

What type of specimens where you able to see under each of the microscopes in the microscope activity

The negative change found inside the plasma membrane is created by potassium ions sodium ions hydrogen ions chlorine ions

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.
