Keywords

Q&A

• What makes amphibians unique?

  Amphibians are unique because they can live both in water and on land. They undergo a remarkable transformation called metamorphosis, where they change from a larval stage (tadpole) to an adult stage with legs and lungs.

• What is the life cycle of a frog?

  The life cycle of a frog begins with eggs laid in water. The eggs hatch into tadpoles, which are aquatic larvae with gills. Tadpoles undergo metamorphosis, developing legs, lungs, and other adult features. They eventually become froglets, which are young frogs, and finally mature into adult frogs.

• What do frogs eat?

  The diet of frogs changes as they progress through their life cycle. Tadpoles are herbivores, feeding on algae and plant matter. As they metamorphose, they become omnivores, eating small aquatic organisms. Adult frogs are carnivores, consuming insects, spiders, worms, and other small invertebrates.

• Is there really a monster in Loch Ness?

  While there are many stories and sightings, there is no scientific evidence to support the existence of the Loch Ness Monster. Scientists believe that what people see might be big waves, floating logs, or large fish.

• What happens when a venomous spider bites?

  When a venomous spider bites, it injects venom into the skin. The venom can cause redness, swelling, pain, and other reactions. Most spider bites are not serious, but it's important to seek medical attention if the bite is severe or if you experience unusual symptoms.

• Why do eyelashes exist?

  Eyelashes protect the eyes from dust, dirt, and other debris, filter sunlight, and trigger a blink reflex when something touches them. They help keep the eyes safe and healthy.
