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:
A. She died shortly after she was last seen.
Explanation:
2 is A the rate decreases as the ph gets higher which is bad. The lower the ph the fast the rate of the enzymes are working
4) would be A as well. The colder the temperature the faster the enzyme will react
Answer:
The root.
Explanation:
The root must be the damaged part of the plant. This is because the root har cells are on the root and no new root cells are produced.

Well, the main function of one of the nucleic acids, DNA serves to store the complete genetic information in the form of nucleotide sequences that can later on be transcribed onto mRNA for manufacturing of proteins at the ribosome. The Nucleic acid of RNA, has one of the functions, just described, mRNA serves as a messenger providing the message of the specific sequence of nucleotides for protein synthesis at the ribosomes from DNA to itself.
