The correct Answer is:
To determine why Suchi's teacher told her that a cow is a mammal, we can break down the characteristics of mammals and how they apply to cows. ### Step-by-Step Solution: 1. **Definition of Mammals**: - Mammals are a class of animals that are characterized by certain features. One of the key features is that they give birth to live young rather than laying eggs. 2. **Reproduction**: - Unlike birds or reptiles that lay eggs, mammals, including cows, give birth to their young. In the case of cows, they give birth to calves, which are baby cows. 3. **Cows and Their Young**: - When a cow gives birth, it does not lay eggs. Instead, it nurtures the developing calf inside its body until it is ready to be born. This is a defining characteristic of mammals. 4. **Skeletal Structure**: - While cows do have a skeleton made of bones, this is not a unique characteristic that defines them as mammals. All vertebrates (animals with a backbone) have a skeleton, so this fact does not specifically classify cows as mammals. 5. **Conclusion**: - Therefore, the reason Suchi's teacher stated that a cow is a mammal is primarily because cows give birth to live young (calves) instead of laying eggs. ### Final Answer: Suchi's teacher told her that a cow is a mammal because cows give birth to live young (calves) instead of laying eggs. ---
