Which of the following refers to an organism that has the following characteristics: Elongated marine worms that live in a chitinous tube that they secrete; the tube is often buried in the ground so that only the lophophore sticks out, and the lophophore contains numerous tentacles?

Which of the following refers to an organism that has the following characteristics: Elongated marine worms that live in a chitinous tube that they secrete; the tube is often buried in the ground so that only the lophophore sticks out, and the lophophore contains numerous tentacles?

A) Bryozoan

B) Phoronid

C) Mollusk

D) Annelid.

The correct answer is option D

Phoronid

Explanation: A Phoronid is a small aquatic animal that filter it's food with a crown of tentacle known as lophophore, A Phoronid body is soft so it builds special structures to support and protect the body,these structures are in form of upright/standing tubes made of chitin (a fibrous substance consisting of complex sugar, polysaccharides).

Phoronids are sometimes known as horseshoe worms and they are found in abundance in shallow marine sediments.

Phoronids are unsegmented and are of member of the invertebrate phylum phoronids.

Phronids

Explanation:

phronids are underwater animals characterized by their ability to filter feed. they feed with their lophophore also known as a crowned tentacle. The lophophore contains cilia at its sides which helps to draw food in.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
