Results

The 2 mL treatment included two wing discs (fig. 6, 7). By 2 hours, wing eversion is clearly visible (fig. 13, 14). After 24 hours, further eversion was observed (fig 19-21).

The 5 mL treatment included a pair of leg discs (fig. 8). After 2 hours of exposure, the tips of the discs appear to protrude further out than initially at 0 hours (fig. 15). After 24 hours of exposure, additional eversion of the legs has taken place (fig. 22).

The 8 mL treatment included a wing, eye, and leg disc (fig. 9-11). The leg disc has everted noticeably by 2 hours (fig. 16), while the eye disc did not change in appearance (fig. 17) (an image of the wing disc at 2 hours was not obtained due to technician oversight). However after 24 hours, the wing, eye, and leg discs have everted dramatically (fig. 23-25).

The control treatment (ethanol) discs showed no dramatic change in appearance during the 24-hour period as expected (fig 12, 18, 26).
