animals with backbone and without backbone and how are they alike?
Answer (1)
Answer:Animals can be broadly classified into two groups:1. Vertebrates (Animals with Backbone)Characteristics:Have a vertebral column (backbone)Have a well-developed internal skeletonInclude mammals, birds, reptiles, amphibians, and fishExamples: humans, dogs, cats, birds, snakes, frogs, fish2. Invertebrates (Animals without Backbone)Characteristics:Lack a vertebral column (backbone)May have an external skeleton (exoskeleton) or hydrostatic skeletonInclude insects, arachnids, crustaceans, mollusks, and moreExamples: insects, spiders, crabs, squids, octopuses, worms• Similarities between Vertebrates and Invertebrates:1. Both are multicellular organisms2. Both have cells with a nucleus and organelles3. Both respond to stimuli and adapt to environments4. Both have metabolic processes (nutrition, respiration, excretion)5. Both reproduce (sexually or asexually)6. Both have sensory organs and nervous systems7. Both have musculature and movement capabilities8. Both have similar basic biochemical processes (DNA, RNA, proteins)Despite their differences, vertebrates and invertebrates share many fundamental biological characteristics, reflecting their shared evolutionary history.#hope it helps
