_______________________ is the gradual change of an organism from baby to adult.
Correct Answer
metamorphosisExplanation
Metamorphosis is the process of gradual change that an organism undergoes from its juvenile or larval stage to its adult stage. This transformation involves significant physical and sometimes behavioral changes. Examples of organisms that undergo metamorphosis include insects, amphibians, and some fish. During metamorphosis, the organism typically goes through distinct stages, such as egg, larva, pupa, and adult. This process allows the organism to adapt to different environments and fulfill different ecological roles as it matures.Rate this question:

The stages of a life cycle of a butterfly: baby, __________, pupa, adult
Correct Answer
larvaExplanation
The stages of a butterfly's life cycle are baby, larva, pupa, and adult. The larva stage refers to the caterpillar stage, where the butterfly is in its immature form and undergoes significant growth and development. During this stage, the larva feeds on leaves and grows rapidly before entering the pupa stage, where it undergoes metamorphosis and transforms into an adult butterfly.Rate this question:

________________ can live in water and land.
Correct Answer
amphibians
amphibianExplanation
Amphibians are able to live in both water and land. They have adaptations that allow them to survive in both environments. They have moist skin that helps them breathe through their skin while in water, and they also have lungs for breathing on land. Amphibians go through a metamorphosis from aquatic larvae to terrestrial adults, allowing them to utilize both habitats. This ability to live in both water and land is what defines amphibians.Rate this question:
- 10.
________________ means that animals can control their own temperature.
Correct Answer
warm bloodedExplanation
Warm-blooded refers to animals that are able to regulate their own body temperature, regardless of the temperature of their environment. This is achieved through internal mechanisms such as metabolism and insulation. Unlike cold-blooded animals, warm-blooded animals can maintain a relatively constant body temperature, allowing them to survive in a wider range of environments. This ability to control their own temperature is crucial for their overall health and survival.Rate this question:

This animals have rubbery eggs.
- A.
Turtle
- B.
Birds
- C.
Duck
- D.
Chicken
- E.
Panda
Correct Answer
A. TurtleExplanation
Turtles have rubbery eggs because they have a leathery shell that allows the eggs to be more flexible and durable. This is important for turtles because they lay their eggs on land, and the rubbery texture helps protect the eggs from cracking or breaking during incubation. Additionally, the rubbery eggs also allow for easier passage through the cloaca, the opening where the eggs are laid.Rate this question:

Correct Answer
C. ReptilesExplanation
Reptiles dominated the earth millions of years ago. During the Mesozoic Era, also known as the Age of Reptiles, reptiles such as dinosaurs were the dominant group of animals. They were well-adapted to various environments and had a wide range of sizes and forms. Reptiles were able to thrive and evolve during this time, occupying different ecological niches and shaping the ecosystems of that era. Mammals, fish, amphibians, and rabbits were present during this time, but they were not as dominant as the reptiles.Rate this question:
