The world-famous hamburger chain, Peat's Patties, has been accused of selling hamburgers that are not actually made
from beef. After multiple complaints, the United States Food Safety and Inspection Service obtained hamburger
samples from Peat's Patties (Peat's Sample A and Peat's Sample B), extracted the DNA from the meat, conducted
genetic sequencing and used the resulting sequences, along with DNA sequence data from other animals, to build a
phylogeny that shows the relationship of Peat's Patties meat to other animals. Use the phylogeny below to determine if
Peat's Patties is guilty of using alternative meat sources in their burgers.
Bison
Cow
Goat
Sheep
2. What type of meat is Peat's Patties using in their hamburgers?
Gopher?
- Pig
Peat's Sample
Gopher
Ground Squirrel
Chicken
Turkey
Rattlesnake
Alligator
Beetle
1. Are Peat's Patties hamburgers made from cow meat? Justify your answer using the phylogeny above and
terminology…
To directly test if multicellularity in yeast can evolve as a response to predation pressure, what kind of experiment should you conduct?
Question 2 options:
Cultivate unicellular yeast in the presence and absence of predators and compare the frequency multicellular clusters in each treatment
Add rotifers to pure cultures of unicellular and multicellular yeast and measure the change in light absorption between unicellular and multicellular cultures over 5 days
Cultivate unicellular and multicellular yeast in the presence of predators and compare their growth rate
Cultivate unicellular and multicellular yeast under the exact same conditions and compare their fitness
