Question

В чём различия между позвоночными и беспозвоночными животными?​

Answer 1

Ответ:

тожто у позвоночних є кістки та позвоночник

а у беспозвоночних немае кісток та позвоночника і вони можуть згинатися в любі сторони

Answer 2

Differences between Vertebrates and Invertebrates

Vertebrates and invertebrates are two major groups of animals that differ in several key aspects. Here are the main differences between vertebrates and invertebrates:

1. Presence of a Backbone: - Vertebrates have a well-developed internal skeleton made of bones or cartilage, which includes a backbone or vertebral column. This backbone provides support and protection for the spinal cord. - In contrast, invertebrates lack a backbone or vertebral column. Their bodies are supported by other structures such as exoskeletons (e.g., insects) or hydrostatic skeletons (e.g., worms).

2. Complexity and Size: - Vertebrates are generally more complex in terms of their anatomy, physiology, and behavior. They often have specialized organ systems and exhibit a higher level of organization. - Invertebrates, on the other hand, exhibit a wide range of complexity, from simple organisms like sponges to more complex ones like octopuses. Invertebrates are also found in a greater variety of sizes compared to vertebrates.

3. Nervous System: - Vertebrates have a well-developed central nervous system, including a brain and a spinal cord. This allows for more complex sensory perception, coordination, and higher cognitive functions. - Invertebrates have a nervous system as well, but it varies in complexity across different groups. Some invertebrates have simple nerve nets, while others have more specialized structures like ganglia or clusters of nerve cells.

4. Reproduction and Development: - Vertebrates generally have internal fertilization and give birth to live young (viviparity), lay eggs (oviparity), or have a combination of both (ovoviviparity). They often exhibit parental care and invest more in the survival and development of their offspring. - Invertebrates have diverse reproductive strategies, including external fertilization, internal fertilization, and asexual reproduction. Many invertebrates lay eggs, but some give birth to live young as well. Parental care is less common among invertebrates.

5. Diversity and Number of Species: - Invertebrates represent the vast majority of animal species, accounting for over 95% of all known animal species. They are incredibly diverse and include groups such as insects, spiders, mollusks, and worms. - Vertebrates, although less diverse in terms of species numbers, still exhibit a wide range of forms and adaptations. They include fish, amphibians, reptiles, birds, and mammals.

Please note that the information provided above is based on general knowledge about vertebrates and invertebrates. For more specific details about particular groups or species, further research is recommended.
