![]() Suggest that molecular information can also be used to discover relationships between organisms. Compile a class list of the kinds of information that the students used to group organisms. Describe how phylogenetic tree building helps us understand how species have developed over time. Engage – Introduce the concept of grouping living things as a means of understanding their relationships. The learning cycle was implemented with the following components. The approach was tested on a single lab section in order to refine the method for broader use in the future. ![]() The learning cycle approach was used to develop an activity for BIO101 nonmajors general biology laboratory. ![]() THE RELATIONSHIPS AMONG LIVING THINGS: DEVELOPING A LAB ACTIVITY. There was no evidence of a significant difference (p<0.05) between the readings of dissolved oxygenįaculty Sponsor: Cox, Amber. We found a significant difference (p<0.05) between the turbidity readings throughout the water systems. All of the data was then uploaded into an SPSS database and analyzed using an ANOVA test. Five readings were recorded at each designated site using a DataMate system connected to a TI-83 calculator. The devise was placed into a variety of aquatic habitats, such as undisturbed drip pools, disturbed drip pools (those with human interaction), and the stream systems running through the cave. The base of each probe was then fitted into a Styrofoam platform that gave rugged structural stability as well as acting as a floatation devise to keep the probes at a standardized depth of one inch below the surface of the water. We designed a self-contained system of Vernier probes that fit snuggly into a water tight canister. However, the primary focus of our research was the development of an apparatus that could be taken into a cave environment to conduct accurate field research. We examined chemical properties such as the amount of dissolved oxygen, calcium levels, ammonium levels, and turbidity in karst streams and drip pools. Our study of water chemistry in karst environments was conducted in order to give us a better understanding of the chemicals and materials that are found in cave water systems. BIO355 MINIPROJECTS: WATER CHEMISTRY OF KARST HABITATS. With the use of various bioinformatics tools found on the internet, three possible gene matches were found and their exon boundaries were determined.įaculty Sponsor: Bugbee, Steve. In this project, through Washington University, a 4,000 base section of Drosophila erecta was selected and its genes were compared to the closely related Drosophila melanogaster. DNA annotation is taking an unknown DNA sequence and comparing it to known sequence to determine locations of genes and functions. BIOINFORMATICS ANNOTATION OF CONTIG-4 IN DROSOPHILA ERECTA. However considerable evidence has been shown that the body tissues were more affected due to the premature death of the experimental snails.įaculty Sponsor: Brown, Adam and Thomsen, Kristin. The tests provided no significant evidence to the correlation between the thickness of the shell and that of lead concentration. The Marisa Cornuarietis were introduced to lead levels of 680 ug/L, 3024 ug/L, 7087 ug/L, 14175 ug/L respectively. ![]() Lead toxicity tests were performed on the Marisa Cornuarietis species of the apple snail family. The snail class Gastropoda includes the Lymnaea and Marisa snails among other pond, garden, apple and freshwater snails. With respect to chronic lead exposure, the Lymnaea Stagnalis is the most sensitive aquatic organism tested to date (Grosell, 2005). It has been found that the Marisa Cornuarietis snail has been affected by certain toxic metals such as lead acetate due to pollution of living environments.
