I believe the essential question is "How is the pig's body similar to our own? Is it?" We have been learning about how the human body functions and it turns out that pigs have similar systems to ours. This was a visual of what we have been learning this unit. My favorite part of the dissection was when we looked at its heart because it is such a vital and intricate organ. I think the dissection clarified some confusing concepts for me and enriched my understanding of the human and pig body.
Our YouTube Video shows our dissection and the organs and systems we found.
1. When you analyzed the results of your gel, did any of your experimental samples contain dyes that did not match the four reference dyes? All of the sample dyes corresponded to a reference dye, however, we found that yellow 5 was not found in any of the sample dyes. 2. Look at the structures of the dyes pictured here. Which of these dyes would migrate similarly to the dyes you examined in this lab? Why? I think blue 1, beetroot red, and carminic acid would travel at similar rates because they are similar sizes. Citrus red 2 and fast green FCF would go at similar paces to the rest of the dyes. 3. Many popular dry dog foods and dog treats have FD&C dyes among their ingredients. For example, Beneful dry food contains Yellow 5, Red 40, Yellow 6, and Blue 2, and Snausages Breakfast Bites contain Red 40 lake, Yellow 6 lake, and Yellow 5 lake. (Lake dyes are the insoluble forms of the FD&C dyes.) Why do dog food manufacturers put artificial food colors in dog food? Dyes are
