4. Here are some other websites your friend could check in order to get additional information about the expedition. Which two would you recommend first and why? (a) List of Supplies for the Expedition at http://www. pbs. org/lewisandclark/inside/idx_equ. html (b) Circa 1803 – Historical Background of the Times at http://www. pbs. org/lewisandclark/inside/idx_cir. html (c) Sacagawea at http://www. pbs. org/lewisandclark/inside/saca. html

b and c

Explanation:

why would you need to know the supplies used?

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
