A female with a deletion of the Xic region of one of her X chromosomes will display what phenotype? Both X chromosomes will be active, which is a lethal condition. She will produce half as much protein as normal for genes found on the X chromosome. She will have mosaic regions throughout her body for all of the genes that are expressed on the X chromosome. She will appear androgynous, have longer limbs than normal, be infertile, and may have impaired mental capability. She will have no apparent phenotype associated with the mutated X ic region. .

A eucalyptus tree has a production value of 216 Joules. A giraffe feeds on the eucalyptus tree and converts 52 Joules of energy into its own biomass (e.g., liver, heart, skin, fat, cells). The remaining energy that the giraffe consumes is lost as heat of aerobic respiration and heat from producing feces and urine. Calculate the trophic level transfer efficiency (TLTE) between the two trophic levels (i.e., eucalyptus tree to giraffe). .

A Different Business Model The vast majority of clothes sold in developed countries were products of a make-to-stock production model in which clothing firms designed pieces in a spectrum of sizes, had them sewn in large quantities in countries with low labor costs, and then pushed them out through their retail channels. Customized, tailor-made clothing followed a make-to-order model. Kane and Badger conceived an approach that stood between mass production and individual customization, adopting beneficial elements of each model. Fula\&Style would sell boxed "kits" of preassembled, 8o-percent sewn fabrics, including zippers, buttons, matching accessories, and clear instructions for the tailor. Customers would take those kits to their favorite tailor, who could complete the production cycle: fitting and sewing (Exhibit 4). The result would be a piece of apparel that fit perfectly yet demanded less of the customer's time and effort than the traditional tailor-made alternative. The suppliers for this alternative kit model-tailors and fabric makers-were plentiful and affordable throughout West Africa. If Fula\&Style were successful, these tailors and local fabric makers would also benefit. Kane and Badger considered the betterment of these suppliers as part of Fula\&Style's mission. Among Senegalese tailors there were no uniform standards for how pieces should be fitted and sewn together or the number of stitches per centimeter. The absence of standards was a potential threat to the quality and consistency of the new company's offerings. Fula\&Style could design in such a way that each kit would contain clear instructions. But would independent tailors follow them to the letter? Would competitors copy their kit-based concept? Like other MIT students, Kane and Badger explained their idea to classmates, hoping for useful feedback. They got some good ideas from classmates, but found most of these discussions frustrating. Kane recalled, "They'd say, "To be successful you have to address either the very bottom or very top of the pyramid. You can't win in the middle.," Kane rejected that Page 4 Fulakstyle Case #1 14 006 conventional thinking and felt that in addressing middle class needs, the venture would create jobs for people at the pyramid's bottom. The MIT Contest Given mixed feedback from their peers, the two students wondered if they were too close to their concept to perceive inherent weaknesses? Could those be improved? One way to find out was to present the company's business plan to more critical eyes and ask for feedback. The MIT Ideas Global Challenge provided an opportunity to do that. The MIT Ideas Global Challenge supported innovation and entrepreneurship through an annual competition that awarded up to \$10,000 USD per team for the best ideas for tackling barriers to human or environmental well-being in communities around the world.s The contest was open to MIT students, faculty, staff, alumni, and their collaborators. From 2001 to 2012.
