On the bahamian island of andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swinm continuously for a long time. when placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. the predatory fish rely on visual cues and speed to capture mosquitofish. mosquitofish rely on speed and visual cues to avoid the predatory fish which adaptations(s) might predators survive in ponds that are home to faster mosquitofish? 1. directional selecfon for increased speed 2. stabilizing selection for speed that matches that of the mosquitofish 3. change in hunting behaviour that replaces reliance on visual cues with reliance on tactile cues, which can be used to hunt at night 4. change in hunting behaviour that eliminates speed in favour of better camouflage, which permits an ambush strategy a. 1 only ob. either 2 or 3 oc.1,3, or 4 od. either 1 or 3 oe.2 only

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
