Question: Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight and enable solar energy to be harnessed at different levels around the world, mostly depending on distance from the equator. Although solar energy refers primarily to the use of solar radiation for practical ends, all renewable energies, other than geothermal and tidal, derive their energy from the Sun in a direct or indirect way.

Answer: Where do the majority of renewable energies derive their energy from?


Question: Serotonin is a neuromodulator involved in regulation of mood and behavior. Development in the limbic system plays an important role in determining rewards and punishments and processing emotional experience and social information. Changes in the levels of the neurotransmitters dopamine and serotonin in the limbic system make adolescents more emotional and more responsive to rewards and stress. The corresponding increase in emotional variability also can increase adolescents' vulnerability. The effect of serotonin is not limited to the limbic system: Several serotonin receptors have their gene expression change dramatically during adolescence, particularly in the human frontal and prefrontal cortex .

Answer: Which neuromodulator is involved in regulation of mood and behavior?


Question: Nicholas felt that, because of Russian assistance in suppressing the Hungarian revolution of 1848, Austria would side with him, or at the very least remain neutral. Austria, however, felt threatened by the Russian troops in the Balkans. On 27 February 1854, the United Kingdom and France demanded the withdrawal of Russian forces from the principalities; Austria supported them and, though it did not declare war on Russia, it refused to guarantee its neutrality. Russia's rejection of the ultimatum caused the UK and France to enter the war.

Answer:
In what year did the Hungarian revolution take place?
