Answer 1

Animals are eukaryotic multicellular organisms that belong to the kingdom Animalia. Animals are also called Metazoan. Different organisms are categorized depending upon the characteristics, structure, and function they exhibit.

Complete answer:
Kingdom Animalia is one of the three kingdoms and it is further divided into different classes. They are Vermes, Insecta, Amphibia, Aves, and Mammals. Lizards are characterized by scaly skin and a long tail and belong to the class of Reptiles. Depending upon the species of lizards, their weight can vary from 500 mgs to 150 kgs. Poisonous lizards are commonly known as Gila monsters and are carnivorous. Heloderma is the poisonous lizard. It is commonly known as Gila monsters and belongs to the species of venomous lizards. It is native to the northwestern Mexican state of Sonora and the southwestern United States. They are a threat to human beings. The Komodo dragon is the dangerous known lizard. Lizards are cold-blooded animals. They require sunlight to survive longer. The tail of the lizard is very much strong and used by them for the defense mechanism.
Therefore, option B: Heloderma – poison gland is the correct match pair.
Chameleons have a squamate vision and not binocular vision. Varanus lizards are also called monitor lizards. These are not poisonous. House lizards belong to the gecko family and are native to tropical areas of Africa and Europe. These species of lizards are called house geckos. Due to the readiness to coexist and adapt to humans they are called house lizards or common wall lizards.

Note: Hemidactylus can be easily seen in human habitations. House lizard is a reptile that possesses three-chambered hearts. Big, stocky, slow-moving reptiles that prefer semi-arid climates are Heloderma, or beaded lizards. Their tails are brief and used as organs for fat storage. Small, non-overlapping, bead-like scales cover them, with osteoderms on the undersides of their bodies. All animals with yellowish or pinkish markings are black in color. The only living genus in the Helodermatidae family is Heloderma.
