Answer:
Dimetrodon (/daɪˈmiːtrədɒn/ (About this soundlisten)[1] or /daɪˈmɛtrədɒn/,[2] meaning "two measures of teeth") is an extinct genus of non-mammalian synapsid that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Ma).[3][4][5] It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first erected in 1878.
Explanation:
Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs. Reptile-like in appearance and physiology, Dimetrodon is nevertheless more closely related to mammals than to modern reptiles, though it is not a direct ancestor of mammals.[4] Dimetrodon is assigned to the "non-mammalian synapsids", a group traditionally called "mammal-like reptiles".[4] This groups Dimetrodon together with mammals in a clade (evolutionary group) called Synapsida, while placing dinosaurs, reptiles and birds in a separate clade, Sauropsida. Single openings in the skull behind each eye, known as temporal fenestrae, and other skull features distinguish Dimetrodon and mammals from most of the earliest sauropsids.

Answer:
Peer review
Explanation:
<em>Before a research can be published, it is subjected to scrutiny by experts that are versed in the same field. The scrutiny ensures that research authors observed the required standards expected in their fields and ensure that personal biases and unwarranted claims are eliminated before the research is published.</em>
This is otherwise known as peer review.
Answer:
ATP uses the energy from ATP hydrolysis and moves ions across the membranes.
Explanation:
- The mechanism of transportation of proteins and ions across cell membrane uses the ATPase that consume the energy from ATP hydrolysis and moves the small molecules across the cell membrane.
- The energy is used against a established electric potential or simply the chemical concentration gradient.
- This mechanism of transportation of ions is the example of active transport and a coupled chemical reaction.
