In one or two sentences, explain how cats and dogs, both mammals, could be classified as distinct animals. What characteristics set them apart from one another?(2 points)
Cats and dogs can be classified as distinct animals based on their physical appearance, behavior, and physiological characteristics such as skeletal structure, digestive system and sensory organs. Some notable differences are that cats have retractable claws and are more independent, while dogs have non-retractable claws and are more social creatures.
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.(2 points)
Advantages of having an exoskeleton include a strong support structure, protection from predators and the environment, and the ability to retain moisture, while disadvantages could include limited mobility due to the weight and thickness of the exoskeleton, and the need to molt and regrow the exoskeleton as the animal grows and develops.
