1) Explain how a symbiosis b/t a single-celled primitive eukaryote and bacteria let do the evolution of the mitochondria and chloroplast. In your explanation, include the benefit that each symbiont conferred to the other. Provide evidence that the two aforementioned organelles have bacterial origins.

Compare the phylogenies ( the cladistics and UPGMA methods). Describe one major difference between the two evolutionary hypotheses that these trees represent. Why do the contrasting philosophies underlying parsimony versus distance methods give you a different phylogeny?

A fly has a genetic mutation that accelerates the breakdown of the period protein. a) How and why would this change circadian rhythms?

b) What do hypothesize the circadian rhythms would look like under normal lighting conditions (12 hours light, 12 hours dark) Describe why this would be

the response. c) What will the circadian rhythms look like under constant dark conditions? Describe why this would be the observation.

Answer this question in a 1-2 paragraphs

The experiment that was performed was size exclusion chromatography. it involved:

- sephadex G75 (separates up to 80,000 g/mol)
- buffer: 20mM sodium Phosphate @ ph 7.0
- three compounds that were separated
1.) blue dextron (2,000,000 g/mol) blue
2.) cytochrome C (~12,000 g/mol) orange
3.) potassium chromate (194.2 g/mol) yellow

1 eluded first followed by 2 and then 3 as expected.

••• Come up with a creative, some sort of experiment that can possibly be performed to consolidate or build on the experiment already performed. “We are not looking for changes for the current experiment, this would be considered minor/ trivial changes and will lead to only 1 point”.
