Answer 1

Vertebrates

Question 2

thing that eats or uses something.

Answer 2

Question 3

a structure containing a number of nerve cell bodies, typically linked by synapses, and often forming a swelling on a nerve fiber.

Answer 3

Question 4

the stomach or belly.

Answer 4

gut

Question 5

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

Answer 5

Coelom

Question 6

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

Answer 6

Bilateral Symmetry

Question 7

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

Answer 7

Radial Symmetry

Question 8

lack of equality or equivalence between parts or aspects of something; lack of symmetry.

Answer 8

Asymmetry

Question 9

a primitive sedentary aquatic invertebrate with a soft porous body that is typically supported by a framework of fibers or calcareous or glassy spicules. Sponges draw in a current of water to extract nutrients and oxygen.

Answer 9

Sponges

Question 10

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

Answer 10

Cnidarians

Question 11

a worm of a phylum which includes the planarians together with the parasitic flukes and tapeworms. They are distinguished by having a simple flattened body which lacks blood vessels, and a digestive tract which, if present, has a single opening.

Answer 11

Flatworms

Question 12

a nematode, especially a parasitic one found in the intestines of mammals.

Answer 12

Roundworms

Question 13

an invertebrate of a large phylum which 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.

Answer 13

Mollusks

Question 14

15. Open circulatory system

Answer 14

Open circulatory system

Question 15

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.

Answer 15

closed circulatory system

Question 16

The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches.

Answer 16

Annelid worms

Question 17

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

Answer 17

Exoskeleton

Question 18

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

Answer 18

Compound eye

Question 19

either of a pair of long, thin sensory appendages on the heads of insects, crustaceans, and some other arthropods.

Answer 19

Antenna

Question 20

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

Answer 20

Metamorphosis

Question 21

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

Answer 21

Endoskeleton

Question 22

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

Answer 22

Water vascular system

Question 23

an animal lacking a backbone, such as an arthropod, mollusk, annelid, coelenterate, etc. The invertebrates constitute an artificial division of the animal kingdom, comprising 95 percent of animal species and about 30 different phyla.

Answer 23

invertebrates
