If the water temperature in a lake drops from 25°c to 10°c, what effect is it likely to have on aquatic animals that have a high demand for dissolved oxygen?
they will find it easier to meet their needs for dissolved oxygen.
they will find it harder to meet their needs for dissolved oxygen.
they will leave the lake and find another with warmer water.
they will adapt to the change in temperature and use more dissolved oxygen.

Which would be an adaptation in a rainforest, but not in a tundra? a. ability to store water for a long time b. fur that blends in with snow c. strong claws for killing prey d. a beak that can dig into thick trees

Long-period comets come from the oort cloud particles in earth’s atmosphere material from the asteroid belt the kuiper belt

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.
