The experiments below show visking osmometers, which are used to measure osmosis. Visking tubes are partially permeable. The experiments below all involve different solutions. They were left for a day. The water level at the start of the day is shown. Mark on each diagram where you think the liquid levels will be after one day.

What happens whenever a net force acts on an object

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
