Q: Q: What do you call the heat below earth's surface that can be used to produce electricity? Read this paragraph and choose the correct option from the provided answers: Heat below Earth's surfacecalled geothermal energy can be used to produce electricity. A power plant pumps water underground where it is heated. Then it pumps the water back to the plant and uses its thermal energy to generate electricity. On a small scale, geothermal energy can be used to heat homes. Installing a geothermal system can be very costly, however, because of the need to drill through underground rocks. Choices: - inert energy - renewable energy - natural energy - geothermal energy A:
A: geothermal energy

Q: Q: Sporangia produce spores that develop into tiny, heart-shaped what? Read this paragraph and choose the correct option from the provided answers: A mature sporophyte fern has the familiar leafy fronds. The undersides of the leaves are dotted with clusters of sporangia. Sporangia produce spores that develop into tiny, heart-shaped gametophytes. Gametophytes have antheridia and archegonia. Antheridia produce sperm with many cilia; archegonia produce eggs. Fertilization occurs when sperm swim to an egg inside an archegonium. The resulting zygote develops into an embryo that becomes a new sporophyte plant. Then the cycle repeats. Choices: - cells - tubules - filaments - gametophytes A:
A: gametophytes
