Insects group of animals is characterized by?

Explanation
Insects are a group of animals that have three pairs of jointed legs, and many of them have one or two pairs of wings . Their body is divided into three main segments: head, thorax, and abdomen. Insects include a wide range of species, some of which suck blood (like mosquitoes) or nectar from flowers (like bees and butterflies). Insects also lay eggs.

Explanation
Mammals are a group of animals that have babies that are born alive (viviparous) , are warm-blooded (endothermic), have mothers that feed their babies with milk (lactation) , and have fur, hair, or skin and a spine (vertebrates). Examples : humans, dogs, cats, bears, whales, dolphins, lions, monkeys, elephants and sharks etc.

Explanation
Permanent magnets are materials that retain their magnetism for a long time. They are typically difficult to magnetize , but once magnetized, they retain their magnetic properties.

Explanation
Birds are a group of animals that lay eggs, are warm-blooded , have either a beak or bill , have feathers on their body, and have a tail, two legs , and two wings. Examples: sparrows, eagles, robins, and ostriches.

Explanation
Reptiles are a group of animals that have dry, scaly skin, are cold-blooded, lay their eggs on land , and live in both water and on land. Examples : snakes, lizards, spider, tortoise, turtles, and crocodiles.

Explanation
Amphibians are a group of cold-blooded animals that live in both aquatic (water) and terrestrial environments (land) . They have moist, smooth skin that helps them to breathe and regulate their body temperature . Examples : frogs, toads, salamanders, and newts.

Explanation
Fish are aquatic animals that live in water, have fins instead of legs, lay eggs in water, have a body covered in scales, and breathe using gills . They are a group of cold-blooded vertebrates that are well adapted to life in water .

Explanation
Warm-blooded vertebrates, also known as endothermic vertebrates. Warm-blooded are animals that maintain a constant body temperature , regardless of the temperature of their surroundings. They are able to generate heat internally and regulate their body temperature, allowing them to maintain a relatively constant body temperature. Examples : birds and mammals.

Explanation
Cold-blooded vertebrates are animals that take on the temperature of their surroundings. They are also known as ectothermic vertebrates . Their body temperature is regulated by the environment around them, and they often bask in the sun or seek shade to control their body temperature. Examples : fish, amphibians, and reptiles.

Explanation
Vertebrates are divided into two main groups based on temperature regulation: Cold-blooded (ectothermic) vertebrates, which include: Fish, Amphibians and Reptiles Warm-blooded (endothermic) vertebrates, which include: Birds and Mammals (including humans)
