Cats and dogs are classified as distinct animals despite being mammals because they have several key differences in their physical and behavioral characteristics.
Firstly, cats are generally smaller than dogs and have a more streamlined body with a longer tail, while dogs come in a wider range of sizes and have a more variable body structure.
Secondly, cats have retractable claws, while dogs' claws are non-retractable.
Thirdly, cats are obligate carnivores, meaning they require a diet of meat to survive, while dogs are omnivores and can eat a wider range of foods.
Fourthly, cats are more independent and solitary animals, while dogs are known for their sociability and are often kept as pets for companionship.
Finally, cats are usually more skilled climbers and jumpers, while dogs are more adept at running and chasing.
Overall, despite being both mammals, cats and dogs have distinct differences in their physical and behavioral characteristics that set them apart as separate species.

Snails and beetles have exoskeletons. Hypothesize the advantages and disadvantages of having an exoskeleton rather than a
backbone. Explain your answer in one or two sentences.
backbone. Explain your answer in one or two sentences.
One advantage of having an exoskeleton is that it provides protection from predators and physical damage, while a disadvantage is that it limits growth and movement flexibility. Another disadvantage of having an exoskeleton is that it leaves the organism vulnerable to desiccation, whereas vertebrates with backbones have internal support systems and are not as vulnerable to changes in water availability.
Vertebrates include fish, amphibians, reptiles, birds, and mammals. Analyze the common characteristics of

explain how they differ from mammals. Explain your answer in one or two sentences.
The common characteristics of vertebrates include having a backbone, a well-developed nervous system, and an internal support system. However, mammals are different from other vertebrates in that they possess hair or fur, have mammary glands for nursing their young, and are warm-blooded with a higher metabolic rate.
