The mesodermal cell which give rise to urinary system in frog are called:

Explanation

Pincer cells are deformed blood cells which are a characteristic feature of hereditary spherocytosis associated with Protein Band-3 deficiency. Therefore, A is incorrect. A blastomere is a type of cell produced by cell division (cleavage) of the zygote after fertilization; blastomeres are an essential part of blastula formation and blastocyst formation in mammals. Therefore, B is incorrect. The nephrotome is a section of the mesoderm that was thought to give rise to the pronephros and eventually to the rest of the kidney. Therefore, A is the correct answer. However, modern visualizing techniques such as scanning electron microscopy have shown this is not the case. Parietal cells (AKA oxyntic cells) are epithelial cells in the stomach that secrete hydrochloric acid (HCl) and intrinsic factors. These cells are located in the gastric glands found in the lining of the fundus and body regions of the stomach.
