The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called <u>vallate</u> papillae.
Explanation:
The shape, location and function of these taste buds make vallate papillae unique. First, they have a distinctive "v" shape, and most adults only have seven to twelve of these papillae, vallate papillae are the least numerous papillae, they are the recipients of the bitter taste. The vallate papillae are the largest and the most specialized, they are located on the back of the tongue, forming the lingual V, in a variable number from 7 to 12. The number of taste buds depends on age, presenting around 270 in the newborn and descending approximately one hundred in individuals older than 75 years. These buttons are located in the crypts or grooves that form the papillae, mainly on their internal face (the annular groove is observed between the papilla and the edge of the calyx), in whose edges the extremities of the taste corpuscles stand out in the form of filaments. Each taste corpuscle comprises two classes of cells: supportive and taste cells.
There are so many examples for that in different areas, like Perylene experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/perylene-cas-198-55-0-item-282870.htm
some gases prevent the escape of heat from the earth.There will be an increase in the percentage of such gases would cause the average temperatures to increase world wide.This is known as greenhouse effect.Carbon dioxide is one of the green house gases.An increase in the carbon dioxide content in the atmosphere woul cause more heat to be retained by the atmosphere and lead to global warming.
It means the entire variability among living organisms. From marine and terrestrial life forms, it also means that each types of these ecosystems hold large diverse species that have even their own subspecies.
