A descriptive generalization about how some aspect of the natural world behaves under stated circumstances. This ultimately implies that, scientific hypotheses are quite different from a scientific theory. But statement B does not have a test that can prove it wrong. Several examples include the idea that living organisms develop from nonliving matter, which formed the basis of spontaneous generation, a hypothesis that ultimately was disproved (first in 1668, with the experiments of Italian physician Francesco Redi, and later in 1859, with the experiments of French chemist and microbiologist Louis Pasteur); the concept proposed in the late 19th century that microorganisms cause certain diseases (now known as germ theory); and the notion that oceanic crust forms along submarine mountain zones and spreads laterally away from them (seafloor spreading hypothesis).
