Figure 3.

The swimming speeds of day 10 adult worms with MeHg increase with time. a, swimming speeds of worms during the first (the first 5 seconds) phase and last (the last 5 seconds) phase of swimming. The dataset is part from Fig. 2 c. b, representatives of swimming speed of day 10 adult worms with developmental MeHg exposure. Each dot represents moving speed of one worm at every 0.1s interval. The parameters used to calculate swimming speed were recorded with the software WormLab for worms swimming in M9 buffer. Swimming speed was calculated as the moving distance of the center point of longitudinal axis of the worm’s body per time unit (0.1 s). All speed data were converted to absolute values. Analyses in a were performed with t-test. *** p<0.001
