Animal Variation And Classification! Trivia Questions

Explanation
The correct answer is vertebrates and invertebrates. This answer is correct because these are the two main divisions of animals based on the presence or absence of a backbone. Vertebrates are animals that have a backbone, while invertebrates are animals that do not have a backbone. This classification is fundamental in the field of zoology and helps to distinguish between different groups of animals based on their anatomical characteristics.

Explanation
Beetle is the correct answer because beetles are insects, and insects have exoskeletons. An exoskeleton is a hard, protective outer covering that provides support and protection for the animal's body. Cats, snakes, and jellyfish do not have exoskeletons.

Explanation
A mule is the cross breed of a horse and a donkey. Mules are typically sterile, meaning they cannot reproduce. They inherit certain characteristics from both parents, such as the strength and endurance of a horse and the intelligence and surefootedness of a donkey. Mules are commonly used as working animals, known for their hardiness and ability to navigate difficult terrain. They are also known for their calm and patient nature, making them popular for riding and packing purposes.

Explanation
The given statement "Fsh is invertebrates" is grammatically incorrect. It should be "Fish are invertebrates." However, this statement is still incorrect because fish are not invertebrates. In fact, fish are vertebrates as they possess a backbone or a spinal column. Therefore, the correct answer is False.

Explanation
Dicots, also known as dicotyledons, are a group of flowering plants that typically have two cotyledons or seed leaves. These cotyledons are the first leaves to emerge from the seed upon germination. They play a crucial role in providing nutrients to the developing plant until it can produce its own food through photosynthesis. This characteristic of having two cotyledons distinguishes dicots from monocots, which usually have only one cotyledon. Therefore, the statement "they usually have two cotyledons" accurately describes dicots.
