Problem: Animals are also involved in the distribution of seeds. Fruit, which is formed by the enlargement of flower parts, is frequently a seed-dispersal tool that attracts animals to eat or otherwise disturb it, incidentally scattering the seeds it contains (see frugivory). Although many such mutualistic relationships remain too fragile to survive competition and to spread widely, flowering proved to be an unusually effective means of reproduction, spreading (whatever its origin) to become the dominant form of land plant life.
What does a plant get out of forming fruit?

Answer: seed-dispersal


Problem: In 1807, Thomas Young was possibly the first to use the term "energy" instead of vis viva, in its modern sense. Gustave-Gaspard Coriolis described "kinetic energy" in 1829 in its modern sense, and in 1853, William Rankine coined the term "potential energy". The law of conservation of energy was also first postulated in the early 19th century, and applies to any isolated system. It was argued for some years whether heat was a physical substance, dubbed the caloric, or merely a physical quantity, such as momentum. In 1845 James Prescott Joule discovered the link between mechanical work and the generation of heat.
Who coined the term "potential energy?"

Answer: William Rankine


Problem: In Theravada Buddhism there can be no divine salvation or forgiveness for one's karma, since it is a purely impersonal process that is a part of the makeup of the universe.[citation needed] In Mahayana Buddhism, the texts of certain Mahayana sutras (such as the Lotus Sutra, the Aṅgulimālīya Sūtra and the Mahāyāna Mahāparinirvāṇa Sūtra) claim that the recitation or merely the hearing of their texts can expunge great swathes of negative karma. Some forms of Buddhism (for example, Vajrayana) regard the recitation of mantras as a means for cutting off of previous negative karma. The Japanese Pure Land teacher Genshin taught that Amitābha has the power to destroy the karma that would otherwise bind one in saṃsāra.
