Researcher recently identified a new species of bird that had purple feathers. After eliminating a purple pigment or porphyrins, they discovered that the purple feather color was due to common structures and pigments present in other birds. Explain the structures and pigments that would produce a purple feather. Be sure to explain what pigment and structures are involved and where in the feather they are located.

Background: From iridescent butterfly wings to brightly colored bird feathers to jet-black mammal hair, animals are capable of producing tissues of nearly every shade of the rainbow. The colors they produce in their tissues result from two categories of mechanisms: pigments and structural colors. Pigments are molecules the differentially absorb and emit wavelengths of visible light. Some pigments (such as melanins) can be produced by most animals, whereas others (such as carotenoids) cannot be produced by vertebrates and must instead...
You have identified a new species of flowering plant with red flowers instead of the usual blue flowers. You performed a cross and found that all of the F1 plants had purple flowers. When you self-fertilized these F1 plants, the resulting F2 was: Blue flowers: 1034 Purple flowers: 297 Red flowers: 94 What would the expected numbers be if these phenotypes were due to two alleles with incomplete dominance at a single loci? What if these phenotypes were due to...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
