Theory because a theory has to be backed up by several experiments
<span>Mammals are advanced synapsids, animals distinguished by having extra openings in the skull behind the eyes; this opening gave the synapsids stronger jaw muscles and jaws (the jaw muscles were anchored to the skull opening) than previous animals.
Synapsids include the mammals, and their ancestors, the pelycosaurs, therapsids, and cynodonts. Pelycosaurs (like Dimetrodon and Edaphosaurus) were early synapsids, they were mammal-like reptiles. Later synapsids include the therapsids and the cynodonts (with multicusped post-canine teeth; they lived from the late Permian through the Triassic period).
The cynodonts led to the true mammals. Over time, the synapsid gait became more upright and tail length decreased</span>
Some isotopes are radioactive, which makes them suitable for medical imaging procedures. Radioactive isotopes have found a wide range of use in medicine. For example, they are used as tracers for diagnostic as well as research on metabolic processes. They are also used in medical imaging procedures, these isotopes include fluorine-18, gallium-67 among many others.
When writing a hypothesis, you need to be able to say IF this, THEN this will happen.
