Hunger Game Questions

1. We simulated evolution by having different variations compete for food. The more food someone got, the more offspring they could have. As the trials progressed, the population began to be almost entirely pinchers.

2. The pincher phenotype was the best because it was the easiest to collect food with. As a result, pinchers could collect more food and have more offspring.

3. Yes, the population was 97% pincher at one point, escalating from 52% just two trials before.

4. The placement of the food was random, giving some people advantages in collecting food. If the food was placed next to someone, they could collect more. That people would have more offspring.

5. If the food was too big for pinchers and knucklers to grab, then stumpys would be the best phenotype. If the food was too small for stumpys to grab, they would have been even less successful.

6. Yes, stumpys would have gone extinct.

7. Natural selection influences how species evolve. Natural selection picks which traits are the most favorable, and evolution is the process of how that species changes.

8. Individuals used their hands instead of just their fingers or knuckles. This made it easier to collect food. It would make that allele more frequent in the coming populations. In nature, organisms will do whatever they can to get a leg up, as was shown in our experiment.

9. Species evolve in evolution. Phenotypes and genotypes evolve because organisms may choose their mate on what makes their offspring survive best or what mate they like the most. One will change the phenotype while the other will change the genotype.

10. How does humans affect natural selection for all species? Do humans' phenotypes or genotypes evolve more?

Candy Electrophoresis Lab

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

Bleaching Jeans!

In the jean lab, we set out to answer what concentration of bleach is best to fade the color out of new denim material in 10 minutes without visible damage to the fabric. Our hypothesis was if bleach breaks down pigments, then the denim will lose its color. We found that the 'best' concentration is dependent on what you're looking for and value. The 100% bleach had the most drastic results with an average of 9 in color removal. In the end, the pigment was more yellow than white. The fabric square was stiffer and the ends were frayed. (The ends were frayed because we cut it. Normally, when bleaching jeans, the hem wouldn't get frayed). This led it to have a fabric damage of 1 1/3. I would consider this one the 'best' because though the fabric turned yellow and is most likely not favorable, it took the color out of the denim. From reliable online sources, you can find data that supports our findings. This also proved our hypothesis because the bleach broke down th
