A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory".
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. [ 1 ] The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science ( physics, chemistry, astronomy, geoscience, biology ).
The systematic, careful collection of measurements or counts of relevant quantities is often the critical difference between pseudo-sciences, such as alchemy, and science, such as chemistry or biology. Scientific measurements are usually tabulated, graphed, or mapped, and statistical manipulations, such as correlation and regression, performed ...
Chemical biology is a scientific discipline between the fields of chemistry and biology. The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems. [ 1 ] Although often confused with biochemistry, which studies the ...
t. e. Vitalism is a belief that starts from the premise that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things." [ 1][ a] Where vitalism explicitly invokes a vital principle, that element is often referred to as ...
AP Chemistry is a course geared toward students with interests in chemical biologies, as well as any of the biological sciences. The course aims to prepare students to take the AP Chemistry exam toward the end of the academic year. AP Chemistry covers most introductory general chemistry topics (excluding organic chemistry ), including: Reactions.
Charles Robert Darwin FRS FRGS FLS FZS JP [ 5] ( / ˈdɑːrwɪn / [ 6] DAR-win; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, [ 7] widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and ...
Advanced Placement ( AP) [ 4] is a program in the United States and Canada created by the College Board. AP offers undergraduate university-level curricula and examinations to high school students. Colleges and universities in the US and elsewhere may grant placement and course credit to students who obtain qualifying scores on the examinations.
