Scientific MethodA logical, systematic approach to the solution of a scientific problem laws/scientific laware not explained scientific theory/theorymust be testable w consistent results -must be falsifiable -cant prove in science but can show results hypothesisa proposed explanation, tries to solve a problem -you can never prove your hypothesis but you can fail to reject -needs to explain the reason for the experiment and the explanation that is being teste

what is the cell theoryall living things are made up of one or more cells and their products cells are the smallest unit that can carry out all life processes all cells come from other cells, they do not come from non-living matter what are prokaryotesthey are organisms that exist as single cells. They do not have a nucleus or other membrane bound organelles. ex archaea and bacteria what are eukaryotesthey are cells that have more complex internal organization. They have a nucleus and ...

Biology - You Is the study of the science of life. It's not just facts and theories. It is also a process. Modem science, including biology, is primarily dependent on inductive logic reasoning, which has given rise to the Scientific Method General methods of critical thinking: Deductive Reasoning - Reasoning from a general premise to a specific conclusion. General methods of critical thinking: Inductive Reasoning - Reasoning from a series of specific facts or observations to a general pri...
