AnswerThese are the enterocoelomates.Starfish, sea urchins are examples.Generally animals of the phyla annelida, molluscs and anthropoda belong to this group.
They are animals formed by enterocoely; in which the mesoderm arises from the wall of the embryonic gut archentron. The latter is an hollow outgrowth which forms the coelom.It is the type of coelom found in deuterostome animals.

Answer:
-Histamine binds extracellularly to the H1 receptor.
-When histamine binds to the H1 receptor. the receptor undergoes a conformation change and binds the inactive G protein.
-Once the G protein is active, it binds to the enzyme phospholipase C, activating it.
-Histamine is likely hydrophilic.
When histamine encounters a target cell, it binds extracellularly to the H1 receptor, causing a change in the shape of the receptor. This change in shape allows the G protein to bind to the H1 receptor, causing a GTP molecule to displace a GDP molecule and activating the G protein. The active G protein dissociates from the H1 receptor and binds to the enzyme phospholipase C, activating it. The active phospholipase C triggers a cellular response. The G protein then functions as a GTPase and hydrolyzes the GTP to GDP. The G protein dissociates from the enzyme and is inactive again and ready for reuse.

Answer:
Scientists use volcanic activity data from this area to show the relationship between volcanic activity and lithospheric plate motion. Hot Spots and Plate Tectonics: A volcanic hot-spot is an area in the mantle from which heat rises in the form of a thermal plume from deep within the Earth. Higher heat and lower pressure at the base of the lithosphere melts rock and forms magma.
