Animal kingdom

Question 1

Vertebrates

Answer 1

an animal of a large group distinguished by the possession of a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fishes.

Question 2

Invertebrates

Answer 2

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.

Question 3

Consumer

Answer 3

things that eat die animals.

Question 4

Ganglion

Answer 4

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

Question 5

Gut

Answer 5

he gastrointestinal tract is an organ system within humans and other animals which takes in food, digests it to extract and absorb energy and nutrients, and expels the remaining waste as feces. The mouth, esophagus, stomach and intestines are part of the gastrointestinal tract.

Question 6

Coelom

Answer 6

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 9

Asymmetry

Answer 9

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

Question 10

Sponges

Answer 10

They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.

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

Question 14

Mollusks

Answer 14

The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species.

Question 15

Open circulatory system

Answer 15

Open circulatory systems 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.
