The observation that supports lophophore evolved more than once is not all lophotrochozoans use a ring of ciliated tentacles for food collection and gas exchange.
<h3>What are lophotrochozoans?</h3>
Lophotrochozoans represent a well-defined group of animals that are characterized to be protostome species.
These animals (lophotrochozoanns) include different taxonomic groups such as, for example, worms or annelids, mollusks, brachiopods, Platyhelminthes, etc.
The lophotrochozoans represent a polyphyletic taxonomic group from a non-strictly evolutionary point of view but instead, composed of species that have a structure referred to as lophophore, a collection of ciliated tentacles surrounding the mouth.
In conclusion, the observation that supports lophophore evolved more than once is not all lophotrochozoans use a ring of ciliated tentacles for food collection and gas exchange.

Answer:
making it hard for bacteria to leave the body
Explanation:
Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.
Chlorophyll may be found in the cytoplasm of a prokaryotic cell
Answer:
Within the geological structure of Cayuga Lake Basin there is a diversity of limestone sources, which would make it possible for the lake to be a good location for the construction of a cement-making plant.
Explanation:
Cayuga Lake, part of the so-called Finger Lakes, located in New York, has an extension of about 40 miles. This lake is of great economic and ecological importance, because it allows fishing and recreation activities, besides being a place of passage for migratory birds.
The Skaneateles, Onandaga, Marcellus, Manilius, Moscow and Tully formations are an important source of limestone of variable quality, from which lime can be obtained for the manufacture of cement.
Although the presence of limestone would be ideal for building a cement-making plant, a project of this size should consider the environmental impact it could have.
