Which of the following best describes the forces that generate solar power? energy of the sun strikes photovoltaic cells producing a flow of electrons. heat energy beneath the earth's surface heats underground water into steam. heat energy is released during nuclear fission and steam is produced to turn a turbine. heat from the earth’s core and pressure transform the remains of dead plants and animals.

The correct answer is the energy of the Sun striking photovoltaic cells producing a flow of electrons.

Explanation:

The radiation from the Sun coming in contact with the photovoltaic cells generating a flow of electrons describes the forces, which produce solar power.  

The heat energy underneath the surface of the Earth, which heats underground water into steam is an illustration of geothermal energy.  

Heat energy discharged at the time of nuclear fission and the generation of steam taking place to start a turbine is an illustration of nuclear power.  

The heat from the core of the Earth and pressure transforming the remnants of dead animals and plants is an illustration of generation of fossil fuels.  

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
