Aglass dish containing a few drops of water in the presence of carbon dioxide gas, nitrogen gas, and small organic compounds is heated by a flame and uv radiation. which early earth scenario does this set-up most closely resemble?
a. amino acid formation from organic molecules in ocean water splashing on hot rock, sand, or clay
b. deep sea volcanoes giving off gases, sulfur, and iron to produce organic molecules
c. lightning in the early atmosphere, which may have produced the first organic molecules
d. the replication of rna near the ocean's surface in the day and night cycling of temperatures

Plz will mark! the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

Which are characteristics of flukes? check all that apply. a they are free living. b they are a type of flatworm. c they reproduce sexually. d they have eyespots. e they are segmented.

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.
