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

Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelid, and cnidarians.

Question 3

Consumer

Answer 3

Consumers constitute the upper trophic levels. Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both. Scientists distinguish between several kinds of consumers. Primary consumers make up the second trophic level.

Question 4

Ganglion

Answer 4

Ganglion cysts are lumps that most commonly develop in the wrist. They’re typically round or oval and are filled with a jelly-like fluid. Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. They also may occur in the ankles and feet

Question 5

Gut

Answer 5

The gastrointestinal tract is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.

Question 6

Coelom

Answer 6

In most animals, Coelom is the main body cavity located in the body to envelop and contain the internal organs, digestive tract etc. It is a hollow, fluid-filled cavity serving as a skeleton.

Question 7

Bilateral Symmetry

Answer 7

symmetry in which similar anatomical parts are arranged on opposite sides of a median axis so that only one plane can divide the individual into essentially identical halves.

Question 8

8. Radial Symmetry

Answer 8

the condition of having similar parts regularly arranged around a central axis.

Question 9

Asymmetry

Answer 9

The lack or absence of symmetry.

Question 10

Sponges

Answer 10

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.

Question 11

Cnidarians

Answer 11

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

Question 12

Flatworms

Answer 12

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.

Question 13

Roundworms

Answer 13

Roundworms are parasites that need to live in the body. These parasitic infections can cause diarrhea and fever. Types of roundworms in humans include pinworms and ascariasis. Often, roundworm infections come from traveling to countries with poor sanitation and hygiene.

Question 14

Mollusks

Answer 14

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.

Question 15

Open circulatory system

Answer 15

Open circulatory systems (evolved in 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

Closed circulatory systems (evolved in echinoderms and vertebrates) 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.
