B. Pumps embedded in the cell membrane
use energy to bring particles into the cell.
C. Particles simply follow the
concentration gradient.
D. Organelles leave the cell, gather
particles, and bring them back into the
cell.
PLEASE HELP ME THANK YOU SO MUCH

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.
