Question

A cylindrical Cnidarian form that has a mouth/anus opening surrounded by tentacles that is attached to a surface and sessile is called the POLYP MEDUSAE whereas the bell-shaped Cnidarian form that has a mouth/anus opening surrounded by tentacles and is free-swimming is called the POLYP MEDUSAE. NEMATODA NEMERTEA is the name for the phylum containing the roundworms. METAMORP1IOSIS ECDYS1S is the process in insects where they transition between one developmental form to another while METAMORPHOSIS ECDYS1S is when the insect sheds its previous exoskeleton to allow it to grow. Echinoderms have an EXOSKELETON ENDOSKELETON. When it comes to body temperature, mammals are considered ENDOTHERMIC EXOTHERMIC and can generate their own heat to regulate their temperature. The name for the incurrent pore in sponges is the OSCULUM OSTIA. Sharks, skates and rays are included in the class OSTEICHTHYES CHONDRICHTHYES because their main skeleton component is BONE CARTILAGE.

Explanation / Answer

36 Ans:

A cylindrical cnidarians from that has a mouth/anus opening surrounded by tentacles that is attached to a surface and sessile is called the Polyp

the bell-shaped cnidariam from that has a mouth /anus opening surrounded by tentacles and is free-swimming is called the Medusae

37 Ans:

The nematodes or round worms constitute the phylum Nematoda

38 Ans:

the process in insects where they transition between one developmental from to another is called metamorphosis

when the insect sheds its previous exoskeleton to allow it to grow is called Ecdysis

39 Ans:

The skeleton of echinoderm is internal that is endoskeleton. It is made of calcium carbonate

40 Ans:

Endothermic animals refers to those are must generate their own heat to maintain their body temperature

41Ans:

The name for incurrent pore in sponge is the osculum, it is a mouthlike aperture in the body wall of a sponge through which water leaves the body cavity

42 Ans:

Sharks, skates and rays are belong to a subclass of chondrichthyes. The class chondrichthyes consist of fish-like marine animals that have skeletons made up of cartilage rather than bone
