Solution for A: A = 3. This can be found by substituting the value of B (2) into the equation A + B = 5. Therefore, A + 2 = 5, and solving for A gives A = 3. Solution for B: B = 2. This can be found by substituting the value of A (3) into the equation A + B = 5. Therefore, 3 + B = 5, and solving for B gives B = 2. Solution for E: E = 7. This can be found by substituting the values of A (3) and B (2) into the equation E = A + B + 2. Therefore, E = 3 + 2 + 2, and solving for E gives E = 7. **

The higher development of vertebrates can be attributed to several key evolutionary adaptations. Vertebrates possess a complex nervous system, including a brain and spinal cord, which allows for more sophisticated behaviors and responses to the environment. Additionally, the presence of a bony skeleton provides structural support and protection for internal organs, allowing for larger body sizes and increased mobility. Vertebrates also have specialized sensory organs, such as eyes and ears, that enable them to gather more detailed information about their surroundings, enhancing their ability to survive and thrive in diverse habitats. **
