The New Philadelphia Science Club is back with another science question in The Times-Reporter. Each week a new science-related question will be given. Everyone is invited to participate by either mailing the answer to the club at the address below or simply emailing the answer to the address given. At the end of the school year several winners will be chosen from all the correct entries submitted to receive a prize. To participate in this drawing, send your answer to:

Last week’s answer
The correct answer to last week’s question is D. All of these are supported.
Ohio University has conducted research studying green, living roofs. Dr. Kim Thompson allowed our NPHS science club students to see some simple examples of how green roof buildings have a more stable temperature in both warm and cold months, improve water quality of the runoff, and reduces the amount of water in the runoff which could reduce flooding. Hearing and seeing aspects of current research was the favorite activity of some of the members interested in ecology and environmental science.
This week’s question
This week Science Club brings you an organism and genetics question. In most biology classes, students hear about a model organism that has been used to study and learn about genetics. This organism has 8 total chromosomes (3 pairs of homologous autosomes and one pair of sex chromosomes). The sex chromosomes are X and Y. XX is a female and XY is male just like humans. Gene linkage was discovered in these organisms. Linked genes are genes that are found on the same chromosome, so they do not independently assort as predicted by Gregor Mendel. They can be used to conduct experiments because their life cycle from fertilized egg to offspring is about 10 days at 25 degrees Celsius. What organism described above is the model organism used both historically and now for genetics studies?
C. fruit flies
