The expected outcome the scientists should observe in the lake suffering from eutrophication after applying ultrasound waves is **lower concentration of nutrients.**

By causing algae cells to sink to the bottom, ultrasound waves lead to a reduction in the algae's presence in the water column. This can result in less decay at the surface, lower nutrient recycling, and ultimately a decrease in the availability of nutrients in the water, thus addressing the problem of eutrophication.
