What are vertebrates?

Vertebrates comprise all animal taxa within the subphylum Vertebrata chordates with backbones, including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described.

All vertebrates are built along the basic chordate body plan: a stiff rod running through the length of the animal vertebral column and or notochord with a hollow tube of nervous tissue the spinal cord above it and the gastrointestinal tract below. In all vertebrates, the mouth is found at, or right below, the anterior end of the animal, while the anus opens to the exterior before the end of the body. The remaining part of the body continuing after the anus forms a tail with vertebrae and spinal cord, but no gut

Vertebrates make up less than five per cent of all described animal species; the rest are invertebrates, which lack vertebral columns.

Dark areas of the map represent places that are very windy. Wind energy is arguably the cleanest source of power. If you were committed to lowering your negative impact on the environment, where could you move to maximize your ability to harvest wind power?

Answers

Answer:

midwestern plains

Explanation:

No map was attached to this picture. Regardless the best place to move to maximize your ability to harvest wind power would be the midwestern plains. These plains are characterized as large open fields that have no trees, buildings, or hills and are usually just flatland with grass. This lack of variable resources gets rid of friction and allows wind to pick up speed in these areas to create a very windy environment. This is the ideal location for wind power.
