A Invasive species can out compete native species when they are introduced outside of their
natural environment. This can threaten a region's
ecosystems, economy, and society. Recently, Canadian
researchers helped identify 15 new bird species
through genetic analysis. Scientists were able to
identify so many new species by analyzing and
comparing the DNA of over 600 North American bird
species. Explain how you think the use of genetic
analysis could help prevent the introduction of new
inyasiye species into Canada.

i thinking chemical change

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
