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). C. He discovered that light and heavy objects gain the same speed when rolling on inclines. a. theories are supported in many ways. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. D. Newton's second law, How much support force acts on a 200-N girl standing on a weighing scale? The investigation of scientific hypotheses is an important component in the development of scientific theory. It's the variable that the experimenter directly manipulates in order to see what happens,. Unless there was a flaw in the testa possibility we should always considera contradictory result means that we can discard the hypothesis and look for a new one. The theory of evolution by natural selection is a classic scientific theory. The alternative hypothesis predicts the opposite: that there will be a difference between the experimental groups. A theory is valid as long as there is no evidence to dispute it. The generation of a hypothesis frequently is described as a creative process and is based on existing scientific knowledge, intuition, or experience.

Hence, hypotheses differ fundamentally from theories; whereas the former is a specific tentative explanation and serves as the main tool by which scientists gather data, the latter is a broad general explanation that incorporates data from many different scientific investigations undertaken to explore hypotheses. The scientific method is used in all sciencesincluding chemistry, physics, geology, and psychology. \rule{2cm}{0.15mm} for the tax hike faced fierce opposition.

Microorganisms (germs, pathogens) are the cause of many diseases through infection. Scientific method: The establishment of scientific theories is accomplished by following the scientific method. Evolution is a change in the characteristics of living things over time. A key function of a hypothesis is to derive predictions about the results of future experiments and then perform those experiments to see whether they support the predictions.
