How Much Do You Know About Worms? Trivia Quiz.

Explanation
The correct answer is 6000. This means that there are approximately 6000 species of worms in the world.

Explanation
Worms breathe through their skin because they do not have lungs or any specialized respiratory organs. Their skin is thin and moist, allowing oxygen to pass through and carbon dioxide to be released. This process is called cutaneous respiration.

Explanation
Worms detect light with their skin. Unlike humans and many other animals, worms do not have eyes or nostrils specifically designed for light detection. Instead, their entire body surface is sensitive to light and can perceive changes in light intensity. This allows worms to respond to light stimuli and adjust their behavior accordingly.

Explanation
Worms have multiple hearts, typically ranging from 5 to 10, depending on the species. These hearts are simple tubular structures that pump blood throughout the worm's body. Having multiple hearts allows worms to efficiently circulate blood and nutrients to all parts of their long, segmented bodies.

Explanation
Worms, specifically earthworms, have an average lifespan of about 2 years. This is determined by studying their life cycle, reproductive patterns, and survival rates in their natural habitat. Earthworms play a vital role in soil health and nutrient cycling, making their lifespan an important factor in understanding ecosystem dynamics.

Explanation
Worms move with their bristles, also known as setae. These bristles are tiny hair-like structures that line the body of the worm. By extending and retracting their bristles, worms are able to grip and push against the ground, allowing them to move forward. This movement is often referred to as peristalsis, which is a wave-like motion created by the contraction and relaxation of the worm's muscles. While worms do have muscles that help with movement, it is primarily their bristles that enable them to navigate their environment.

Explanation
The statement "Worms are hermaphrodite" is false. While it is true that some species of worms, such as earthworms, are hermaphrodites, not all worms share this characteristic. There are many different types of worms, and their reproductive systems can vary greatly. Some worms are dioecious, meaning they have separate male and female individuals, while others are parthenogenic, meaning they can reproduce asexually without the need for a mate. Therefore, it is incorrect to assume that all worms are hermaphrodites.

Explanation
This statement is true. Worms have been on Earth for over 600 million years, while dinosaurs appeared around 230 million years ago. Therefore, worms are indeed older than dinosaurs.

Explanation
The statement "90% of the worm's body is filled with water" is true. This means that the majority of a worm's body is made up of water. This is because water is essential for the survival and functioning of all living organisms, including worms. Water helps to maintain the worm's internal balance, transport nutrients and waste, and regulate body temperature. Therefore, it is accurate to say that a significant portion of a worm's body is composed of water.

Explanation
Worms do not regulate their body temperature. Unlike warm-blooded animals, worms are ectothermic, which means their body temperature is determined by the surrounding environment. They cannot generate internal heat or actively adjust their body temperature. Therefore, the correct answer is that worms do not regulate their body temperature.
