On Thursday, October 3rd, we finished up our Brine Shrimp lab. After collecting our final data and calculating the percent survival rates in the different salt-concentrated water, Brian and I calculated that the 0.5% salt-concentrated water had the highest survival rate. This would suggest that the majority of Brine Shrimp are adapted to survive in bodies of water similar to this example.
After finishing this lab, we did another lab, which showed how the animals that were not naturally selected to survive would die out. This could be caused by a gene that changes the animals appearance or features. For example, tigers that genetically have thin fur will die out in cold weather, will tigers with thick fur will survive. We represented this process by using two different colored beads.
We took the last moments of class taking a quiz on mutations, hereditary traits, ect.
