How does the warm air over the ocean contribute to the formation of hurricanes?

• Storms which form along the equator travel to cooler ocean waters.

• Air and water from the ocean spin to Earth’s rotation and create a spiral effect.

• Heat and evaporating water from the ocean surface provide energy for hurricanes.

• Ocean waters create high air pressure that builds upward with surrounding cool air.

Uneven heating of Earth causes convection currents.

What part of this process is being demonstrated in this diagram?

• Heat causes gases to expand.

• Heat causes gases to contract.

• As air cools, currents flow clockwise.

• As air cools, currents flow counterclockwise.

How does a heat engine operate?

• It uses heat to do work, and leftover heat is exhausted into a cold reservoir.

• It uses radiant energy to do work, and leftover heat is exhausted into a cold reservoir.

Jayson heated two beakers. Each beaker held 100 mL of water. The water began to boil. Then Jayson loosely wrapped one of the beakers in five layers of aluminum foil. He left the second beaker unwrapped. He measured the temperatures of the water in the beakers over time and recorded his data in the table.

Which statement BEST explains Jayson’s observations?

• Aluminum foil is a good conductor of thermal energy.

• The layers of aluminum foil absorbed heat instead of transferring it.

• Layers of air between the foil wrappings reduced the transfer of heat.

• The warmer atmosphere around the foil-wrapped beaker prevented the transfer of thermal energy.

Coal, oil, and natural gas have high potential energies, which makes them valuable energy resources. In order to benefit from the energy available in these fossil fuels, the potential energy is converted most directly into which type of energy?

• chemical

• electrical

• solar

• thermal

How does the micronucleus of a Paramecium differ from the nucleus of other protist species?

• A Paramecium can exchange micronuclei to keep the population genetically diverse.

• A Paramecium uses micronuclei as replacements in case the macronucleus is damaged.

• A Paramecium relies on the micronuclei to keep its cilia beating at the same time.

• A Paramecium uses the micronuclei to digest genetic material from bacteria it eats.
