Organic Compounds In Cyanea Capillata And Chrysaora Quinquecirrha, Kris Mitchell '98
Organic Compounds In Cyanea Capillata And Chrysaora Quinquecirrha, Kris Mitchell '98
Honors Projects
Cyanea capillata and Chrysaora quinquecirrha are two species of jellyfish which emit an "iodoform-like" odor. Attempts to identify the compound(s) which produce this odor have been made using chromatography techniques. Thus far, results obtained from column chromatography and GC-MS analysis have been inconclusive. However, these data suggest an hypothesis that may explain the origin of the odor. A low molecular-weight, highly volatile compound, such as ethylene, is a likely candidate for this elusive, odor-causing chemical.
The Characterization Of The Ty5 Strain Of Chamydomonas Reinhardtii, A Chlorophyll Biosynthetic Mutant, Robert Graham '98
The Characterization Of The Ty5 Strain Of Chamydomonas Reinhardtii, A Chlorophyll Biosynthetic Mutant, Robert Graham '98
Honors Projects
Chlorophyll is the light harvesting molecule for many photosynthetic organisms. As a result, chlorophyll is an extremely important molecule, directly or indirectly, to nearly all life. The production of chlorophyll involves a long and complex pathway. The conversion of protochlorophyllide to chlorophyllide is one of the final steps in chlorophyll biosynthesis. Some of the factors affecting the regulation of this process were the focus of this project.
The Role Of The Comstock-Kellogg Glands In Egg Tanning In Romalea Guttata, Elizabeth A. Elasser '98
The Role Of The Comstock-Kellogg Glands In Egg Tanning In Romalea Guttata, Elizabeth A. Elasser '98
Honors Projects
FreshIy laid eggs of the Eastern Lubber grasshopper, Romalea guttata, are yellow and soft-shelled, but within several hours the eggs become hardened and dark brown. In a similar process, calyx and oviduct secretions, which from the egg pod, become frothy, darkened, hardened, and water insoluble during oviposition. It has been suggested that secretions from the paired Comstock-Kellogg glands accelerate tanning of both the eggs and egg pod foam. I investigated the effects of Comstock-Kellogg gland secretions on the rate of egg and egg pod tanning during egg pod production in the female Eastern Lubber grasshopper, R. guttata. Eggs streaked with …
