Question 1

Animals with back bones.

Answer 1

Vertabtrates

Question 2

Animals without back bones.

Answer 2

Invertabrates

Question 3

consumer in Science Expand. consumer. (kən-s ‘mər) A heterotrophic organism that feeds on other organisms in a food chain. ◇ Herbivores that feed on green plants and detritivores that feed on decaying matter are called primary consumers.

Answer 3

Consumer

Question 4

2a: a mass of nerve tissue containing cell bodies of neurons that is located outside the central nervous system and forms an enlargement upon a nerve or upon two or more nerves at their point of junction or separationb: a mass of gray matter within the brain or spinal cord : nucleus 2—see basal ganglion.

Answer 4

Ganglion

Question 5

the alimentary canal, especially between the pylorus and the anus, or some portion of it.

Answer 5

Gut

Question 6

The coelom (/ˈsiːləm/ SEE-ləm, plural coeloms or coelomata /siːˈloʊmətə/ see-LOH-mə-tə) (Greek koilōma, hollow, cavity) refers to the main body cavity in most multicellular animals and is positioned inside the body to surround and contain the digestive tract and other organs.

Answer 6

Coelom

Question 7

Symmetrical arrangement of an organism or part of an organism along a central axis, so that the organism or part can be divided into two equal halves. Bilateral symmetry is a characteristic of animals that are capable of moving freely through their environments. Compare radial symmetry.

Answer 7

Bilateral symmetry

Question 8

Symmetrical arrangement of parts of an organism around a single main axis, so that the organism can be divided into similar halves by any plane that contains the main axis. The body plans of echinoderms, ctenophores, cnidarians, and many sponges and sea anemones show radial symmetry. Compare bilateral symmetry.

Answer 8

Radial symmetry

Question 9

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

Answer 9

Asymmetry

Question 10

any aquatic, chiefly marine animal of the phylum Porifera, having a porous structure and usually a horny, siliceous or calcareous internal skeleton or framework, occurring in large, sessile colonies.

Answer 10

Sponges

Question 11

Cnidaria is a phylum containing over 10,000 species of animals found exclusively in aquatic environments: they are predominantly marine species. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey.

Answer 11

Cnidarians

Question 12

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

Answer 12

Flatworms

Question 13

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

Answer 13

Roundworms

Question 14

The molluscs or mollusks /ˈmɒləsks/ compose the large phylum of invertebrate animals known as the Mollusca. Around 85,000 extant species of molluscs are recognized.

Answer 14

Mollusks

Question 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.

Answer 15

OCS

Question 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.

Answer 16

CCS

Question 17

The annelids, also known as the ringed worms or segmented worms, are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches.

Answer 17

Annelid worms

Question 18

each of the parts into which something is or may be divided.

Answer 18

Segments

Question 19

An exoskeleton (from Greek έξω, éxō “outer” and σκελετός, skeletos “skeleton”) is the external skeleton that supports and protects an animal’s body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as “shells”.

Answer 19

Exoskeleton

Question 20

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

Answer 20

Compound eye

Question 21

(pl) -nae (-naɪ). one of a pair of mobile appendages on the heads of insects, crustaceans, etc, that are often whiplike and respond to touch and taste but may be specialized for swimming or attachment

Answer 21

Antenna

Question 22

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal’s body structure through cell growth and differentiation.

Answer 22

Metamorphosis

Question 23

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

Answer 23

Endoskeleton

Question 24

The water vascular system is a hydraulic system used by echinoderms, such as sea stars and sea urchins, for locomotion, food and waste transportation, and respiration. The system is composed of canals connecting numerous tube feet.

Answer 24

water vascular system
