What keeps all of the planets in the solar system from leaving their orbits around the Sun? *

A: The repulsion of each planet's magnetic field keeps the planets in orbit.

B: The gravitational pull of the Sun keeps the planets from leaving their orbits.

C: The gamma, infrared, and radio waves being emitted from each planet create a path
for it to orbit the Sun.

CD: The gravitational pull of each planet provides just enough force to keep them apart
from one another but still in orbit around the Sun.

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.
