Science (Metamorphosis/Class Of Animals)

In complete metamorphosis, the life cycle of an organism consists of four distinct stages: egg, larva, pupa, and adult. The first stage is the egg, where the organism is in its earliest form and has not yet hatched or developed further. Therefore, the statement that the first stage in complete metamorphosis is the egg is correct.

Complete metamorphosis is a type of metamorphosis that occurs in insects, such as butterflies and beetles. It consists of four distinct stages: egg, larva, pupa, and adult. In each stage, the insect undergoes significant changes in its form and structure. Therefore, the statement that complete metamorphosis has four stages is true.

The correct answer is Nymph, Pupa, Egg. The stage in an insect's life between larva and adult is called the nymph stage. During this stage, the insect goes through several molts and gradually develops into its adult form. The pupa stage comes after the nymph stage, where the insect undergoes a transformation inside a protective casing before emerging as an adult. The egg stage is the initial stage of an insect's life, where it is laid by the adult and eventually hatches into a larva.

The correct answer is "egg, larva, pupa, adult". This is the correct sequence of stages in complete metamorphosis. In this type of metamorphosis, the organism goes through distinct and dramatic changes in its appearance and behavior as it progresses through these stages. It starts as an egg, then hatches into a larva, which is often a worm-like or caterpillar-like form. The larva then undergoes a period of transformation inside a pupa, during which its body undergoes significant changes. Finally, it emerges from the pupa as an adult, with fully developed characteristics and reproductive abilities.

Incomplete metamorphosis actually has 3 stages, not 4. These stages are egg, nymph, and adult. Incomplete metamorphosis is a type of development seen in certain insects where the young nymphs resemble miniature versions of the adult and go through a series of molts until they reach full maturity. Therefore, the correct answer is False.

The stage in an insect's life after it hatches from the egg during complete metamorphosis can be either pupa, larva, or nymph. In complete metamorphosis, the insect goes through four distinct stages: egg, larva, pupa, and adult. After hatching from the egg, the insect enters the larval stage where it undergoes significant growth and development. Following the larval stage, the insect enters the pupal stage where it undergoes a transformation into its adult form. In some insects, like dragonflies, the stage after hatching is called the nymph stage, which is similar to the larval stage but with some differences in physical appearance.

The correct answer is mammal. Mammals are animals that have a backbone and hair. Reptiles and arthropods also have a backbone, but they do not have hair.

An animal with a backbone that lives part of its life cycle in water and part on land is either a reptile or an amphibian. Reptiles, such as turtles and crocodiles, are cold-blooded animals that lay eggs on land and have scales or bony plates on their bodies. Amphibians, such as frogs and salamanders, are also cold-blooded and lay eggs in water. They start their lives as aquatic larvae, then undergo metamorphosis to become terrestrial adults. Elephants, on the other hand, are mammals and do not have a life cycle that involves living in water.

The question asks for an example of an invertebrate. Invertebrates are animals that do not have a backbone. Skunks and eagles are vertebrates, meaning they have a backbone, so they are not examples of invertebrates. On the other hand, worms are invertebrates as they do not possess a backbone. Therefore, worms are the correct answer as they fit the criteria of being an invertebrate.
