A caterpillar undergoes a process called metamorphosis and changes into a butterfly. During this transformation, the caterpillar forms a chrysalis or cocoon and undergoes a complete restructuring of its body. It then emerges as a beautiful butterfly with wings.

Oxygen is the gas in the air that keeps us alive. It is essential for the process of respiration, where it is used by our cells to produce energy. Without oxygen, our bodies would not be able to function properly, leading to serious health problems and eventually death.

Kangaroos are normally found in Australia. Australia is known for its diverse wildlife, and kangaroos are one of its most iconic animals. They are native to the continent and can be found in various habitats across the country, including grasslands, forests, and deserts. Kangaroos have adapted well to the Australian environment and are well-known for their unique hopping locomotion. They play a significant role in the country's ecosystem and are a symbol of its natural heritage.

When a solid such as ice is melted, it undergoes a phase change and transforms into a liquid. This occurs when heat is applied to the solid, causing the molecules to gain energy and move more freely, breaking the rigid structure of the solid and forming a liquid. Therefore, the correct answer is that the solid changes to a liquid when melted.

There are 8 planets in our solar system. This is based on the current definition of a planet, which states that a planet is a celestial body that orbits the Sun, is spherical in shape, and has cleared its orbit of other debris. In 2006, Pluto was reclassified as a "dwarf planet," leaving us with 8 recognized planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Asia is the largest continent on Earth because it has the highest land area and population compared to other continents. It spans over 17.2 million square miles and is home to more than 4.6 billion people. It is geographically diverse, with a wide range of landscapes including mountains, deserts, plains, and forests. Asia is also known for its rich cultural heritage and history, with numerous ancient civilizations and modern economic powerhouses.

Queen bees are the only bees in a hive that can lay eggs. They are incredibly productive and can lay up to 2,000 eggs per day on average. However, during peak seasons, a queen bee can lay as many as 3,000 eggs per day. This high rate of egg-laying is essential for the survival and growth of the bee colony. Therefore, the answer of 1000 – 3000 is the most accurate range for the number of eggs a queen bee lays each day.

Venus is the correct answer because it has the highest average surface temperature of any planet in our solar system. This is due to its thick atmosphere, which traps heat from the sun and creates a greenhouse effect. The surface temperature on Venus can reach up to 900 degrees Fahrenheit (475 degrees Celsius), making it the hottest planet.

Octopuses have three hearts. Two of the hearts pump blood to the gills, while the third heart pumps blood to the rest of the body. This allows for efficient oxygenation and circulation in their unique physiology.

Bees' wings beat at a speed of 180 times per second. This rapid wing movement enables bees to generate enough lift to hover and fly. The high frequency of wing beats also allows bees to control their flight direction and navigate through their environment with precision. This fast wing beating is essential for their foraging activities, as it enables them to quickly move from flower to flower in search of nectar and pollen.
