And, the answer for the the question is :
Explanation:
For tens of millions of years as they branched off from reptiles, the ancestors of all modern mammals were cold-blooded. Mammals and birds alike are classified as “homeotherms” because of their ability to generate their own body heat.
Mammals are a diverse and fascinating group of animals that are characterized by a number of unique traits, including the presence of hair or fur, the ability to produce milk to nourish their young, and the possession of a four-chambered heart. One of the most important and distinguishing characteristics of mammals is their warm-bloodedness, or the ability to maintain a relatively constant body temperature regardless of their environment. This means that no mammal is cold-blooded.
Cold-blooded animals, such as reptiles and amphibians, are unable to regulate their body temperature internally and instead rely on external sources of heat or cold to regulate their metabolism and activity levels. In contrast, mammals are able to maintain a constant internal body temperature through a process known as thermoregulation.
Mammals are able to thermoregulate by a variety of means, including shivering to generate heat, sweating or panting to cool down, and adjusting their metabolism to meet the demands of their environment. This ability to maintain a constant body temperature allows mammals to thrive in a wide range of environments, from the freezing cold of the Arctic tundra to the scorching heat of the desert.
mammals are also known for their diverse and varied lifestyles. There are over 5,500 species of mammals known to science, ranging from tiny shrews that weigh just a few grams to massive whales that can grow up to 100 feet in length. Mammals inhabit nearly every corner of the globe, from the deepest oceans to the highest mountains.
all mammals share certain common characteristics, including the presence of hair or fur, the ability to produce milk to nourish their young, and the possession of a specialized jaw joint that allows for efficient chewing and digestion. These traits, along with their warm-bloodedness, help to distinguish mammals from other groups of animals and have allowed them to become one of the most successful and dominant groups of organisms on the planet.
the statement that no mammal is cold-blooded is true and is one of the defining characteristics of this diverse and fascinating group of animals. From tiny shrews to massive whales, mammals are able to thrive in a wide range of environments thanks to their ability to maintain a constant internal body temperature. Whether in the freezing cold of the Arctic or the scorching heat of the desert, mammals have adapted and evolved to become one of the most successful and dominant groups of organisms on Earth.
