Answer:
A. ATP is a polymer of phosphates.
Explanation:
ATP is not a polymer of phosphates. It is a rather a complex organic molecule that has its main function to provide energy.
Starch and glycogens are polysaccharides or polymers of glucose or simply put, they have glucose subunits.
Nucleotides are biological molecules consisting of 3 major sub units which are the nitrogenous base, the phosphate acid and the 5 carbon (ribose) sugar. They are the building blocks of DNA and RNA and hence monomers.
Amino acids are basically organic compounds that contain amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to every amino acid molecule. They are bond together by a peptide bond between the -NH2 and -COOH group to furthet form polypetides. Proteins in the same vein are called polypeptides which is a chain of amino acids.
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 pollen grain from one flower fertilizes another flower, resulting in the development of a seed.
A frog releases sperm over eggs that were laid by another frog, and these cells fuse together.
Explanation:
Sexual reproduction is brought about by fusion of male and female gametes. Reproduction where a part of an existing organism develops into another organism is asexual.
