Most animal, insect, and plant species reproduce in pairs, or twos. In sexual reproduction, two individuals of the same species each contribute a half-set of their genes. Thus, in their whole set of genes, offspring inherit, or receive from their parents, a mixture of traits. Write down some traits that parents pass on to their offspring. In what ways do these traits help a species survive? Use the box below for your ideas.

How can antibodies "remember" a particular bacterial invader or "antigen" on that invader?

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.

Why do oceanic plates tend to subduction when colliding with a continental plate
