Forming a Good Hypothesis for Scientific Research.
For example, there are many eukaryote examples of bacteria as endosymbionts or endoparasites, but none known in archaea. Strictly post-hoc hypotheses that ignore this third criterion should be avoided.Examples of an If, Then Hypothesis. If you get at least 6 hours of sleep, you will do better on tests than if you get less sleep. If you drop a ball, it will fall toward the ground. If you drink coffee before going to bed, then it will take longer to fall asleep.A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event. A useful hypothesis is a testable statement which may include a prediction. The key word is testable. That is, you will perform a test of how two variables might be related. This is when you are doing a real experiment. You are testing variables.
Hypothesis Examples Hypothesis: All forks have three tines. Disproven if you find any fork with a different number. Hypothesis: There is no relationship between smoking and lung cancer. Hypothesis: Plants require liquid water to survive. Hypothesis: Cats do not show a paw preference (cat.Third, accounting for past events by processes observed in modern cells is preferable to postulating unknown processes that have never been observed. For example, there are many eukaryote examples of bacteria as endosymbionts or endoparasites, but none known in archaea. Strictly post-hoc hypotheses that ignore this third criterion should be avoided.
A new hypothesis for the origin of eukaryotic cells is proposed, based on the comparative biochemistry of energy metabolism. Eukaryotes are suggested to have arisen through symbiotic association.
