The junctional epithelium or attachment epithelium provides a seal at the base of the sulcus.

It's because the oral cavity all the way to the anus is "open" to the external environment. Internal body cavities are those that are completely walled off from the external environment by well defined structures such as skin, mysentary, etc. In contrast the GI tract is specifically designed to periodically open to the external environment an allow food to enter and waste to leave.
Cylinders are basically pipe, or tube shaped. To make them useful they have to be sealed off at at least one end. And the part that seals them off, where you often finds valves and stuff, is called a cylinder head.
push them...i think
push them to the edge
Yes, there are seals in Massachusetts. They can be found along the coast, particularly on islands like Monomoy and Muskeget. Seals are often spotted basking on rocks or swimming in the waters off the coast of Massachusetts.
well for the most part, recycle. almost all of our trash that we dont recycle ends up in our oceans, the killer whale's main food source,seals, eat fish. so colored trash can look like fish, and the seals eat it. and if too many seals eat the trash, they die off, so the killer whales have nothing to eat.
Use a steam cleaner then dry the seals. It always works
No. If you do they will cut off your arm and feed you to the SEALS......
When part of the cell membrane pinches off, it forms a small vesicle called an endocytic vesicle. This process is known as endocytosis and allows the cell to engulf and internalize molecules or particles from its external environment.
