Taste receptors are modified elongated epithelial cells that are present on the tongue, tonsils, pharynx, epiglottis, and hard and soft palates throughout the oral cavity. Regional gene expression around taste buds regulates their formation and is in part regulated by innervating nerves.
Taste pores are openings in the epithelium for chemical substances to enter. Peripheral sensory innervation is through branches of three cranial nerves: facial (VII), glossopharyngeal (IX), and vagal (IV) (X). Only three of the four morphologically unique forms of lingual papillae—the fungiform, foliate, and circumvallate papillae—bear taste receptors.

The Cambrian Explosion (542-488 million years ago) is one of evolutionary biology's greatest mysteries. It was only during this period that complex organisms became widespread and diversified.
The scale of this event can be understood from the contrast between the biota and the extent of fossil diversity on the left and right. Cambrian paleontology has made great strides over the past century. In particular, well-preserved molluscs were found in the Middle Cambrian Burgess Shale and Lower Cambrian Motianshan Shale sediments. The Cambrian side of the "Cambrian Explosion" is more abundantly depicted, contrasting with the Precambrian side. These extremely well-preserved fossil organisms are very difficult to study. The main challenge is her three-dimensional reconstruction and determination of the cellular tissue pattern of the Okina embryo and the fossil-buried structure of the Maotianshan shale.

An insulinoma is a cancerous mass of pancreatic beta cells that secrete insulin but do not respond to feedback mechanisms. How you would expect an insulinoma to affect blood glucose levels and liver activity?
When an excess of insulin is produced, blood glucose levels drop below physiologically normal levels, which stimulates the liver to produce glycogen, which in turn impacts blood glucose levels and liver function.
How insulinoma affect blood glucose?A pancreatic tumor called an insulinoma will encourage the alpha cell synthesis of pancreatic glucagon and enhance the breakdown of glycogen. As a result, it has negative effects on the liver.Glucagon interacts with the liver to raise blood sugar levels, whereas insulin lowers blood sugar levels. Insulin and glucagon work together to manage blood sugar levels.These hormones will control the synthesis of glycogen. The hormones insulin and glucagon regulate the availability of glucose by controlling the synthesis and breakdown of glycogen.The pancreas produces insulin, which is what keeps blood sugar levels in check. Insulinomas create hypoglycemia, or low blood sugar, by producing more insulin than the body needs.

How is the cell cycle important to the processes of mitosis and meiosis
Answer:
Living things need both meiosis and mitosis to function.
In order for the body to grow, mitosis takes place. Mitosis is what causes us to grow from the size of a baby to the size of an adult. The cell creates a copy of itself during mitosis, enabling the organism to grow larger through repeated mitotic divisions. In order to replace damaged or dead cells, mitosis also takes place. Without mitosis, cells cannot be repaired or grown.
