Q-1 Why does a platypus have such a strange body shape, like a duck's bill and webbed feet, even ...
Ans-1 The platypus has evolved its unique body shape to adapt to its semi-aquatic lifestyle. The duck-like bill is used for hunting underwater, sensing prey through electroreception. Webbed feet help it swim efficiently, and the ability to lay eggs is a characteristic of monotremes, an ancient group of mammals to which the platypus belongs. These adaptations allow the platypus to thrive in its specific ecological niche.

How does the circulatory system of a fish differ from that of a mammal?
How does the circulatory system of a fish differ from that of a mammal?
Fish have a simpler, two-chambered heart and use gills to extract oxygen from water. They have a single-loop circulatory system. Mammals, including humans, have a more complex four-chambered heart, breathe air with lungs, and have a double-loop circulatory system. Mammals are typically more efficient and can regulate their body temperature, while fish cannot.
