the body cavity in metazoans, located between the intestinal canal and the body wall.

Question 7

Bilateral Symmetry

Answer 7

the property of being divisible into symmetrical halves on either side of a unique plane.

Question 8

Radial Symmetry

Answer 8

symmetry around a central axis, as in a starfish or a tulip flower.

Question 10

Sponges

Answer 10

Sponges, the members of the phylum Porifera, are a basal Metazoa clade as sister of the Diploblasts.

Question 11

Cnidarians

Answer 11

an aquatic invertebrate animal of the phylum Cnidaria, which comprises the coelenterates.

Question 12

Flatworms

Answer 12

The flatworms, flat worms, Platyhelminthes, Plathelminthes, or platyhelminths are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates.

Question 13

Roundworms

Answer 13

The nematodes or roundworms constitute the phylum Nematoda. They are a diverse animal phylum inhabiting a broad range of environments.

Question 14

Mollusks

Answer 14

an invertebrate of a large phylum that includes snails, slugs, mussels, and octopuses. They have a soft, unsegmented body and live in aquatic or damp habitats, and most kinds have an external calcareous shell.

Question 15

Open circulatory system

Answer 15

Open circulatory systems (evolved in crustaceans, insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.

Question 16

Closed circulatory system

Answer 16

Vertebrates, and a few invertebrates, have a closed circulatory system. Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities.

Question 17

Annelid worms

Answer 17

Annelid. The annelids (Annelida, from Latin anellus, “little ring”), also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches.

Question 18

Exoskeleton

Answer 18

a rigid external covering for the body in some invertebrate animals, especially arthropods, providing both support and protection

Question 19

Compound eye

Answer 19

an eye consisting of an array of numerous small visual units, as found in insects and crustaceans.

Question 20

Antenna

Answer 20

In radio an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.

Question 21

Metamorphosis

Answer 21

(in an insect or amphibian) the process of transformation from an immature form to an adult form in two or more distinct stages.

Question 22

Endoskeleton

Answer 22

an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates.

Question 23

Water vascular system

Answer 23

(in an echinoderm) a network of water vessels in the body, the tube feet being operated by hydraulic pressure within the vessels.
