Answer:
How do nutrients move through an environment? What drives the movement of nutrients?
My answer 6b: Nutrients are often transported across the environment by migrating from the physical environment into living creatures and then being recycled back into the physical environment. For example, an animal could receive nutrition by eating plants. To stay alive, the animal uses the chemical energy gained from the food. When the animal dies, the nutrients in its body return to the soil and are re-absorbed by plants. The transport of nutrients in the ecosystem is driven by nutrient cycles.
Answer:
There are 5 sacral vertebrae that are fused into<u> one </u>sacrum. There are <u>seven</u> cervical vertebrae, some of them containing a transverse foramen. There are <u>twelve </u>thoracic vertebrae, most of them with a long spinous process. The vertebral column is composed of <u>thirty-three</u> vertebrae distributed into 5 regions. There are <u>three </u>to 5 bones in the coccyx, with variability in the fusion. There are <u>five</u> lumbar vertebrae, which have large vertebral bodies.
Explanation:
The vertebral column has 33 vertebras and five sections. They are the cervical spine with seven vertebrae, the thoracic spine with twelve vertebrae, the lumbar spine with five vertebrae, the sacrum with five fused vertebrae, and lastly, the coccyx with three to five vertebrae. The vertebrae in each section have different characteristics. For example, the length of the spinous process changes becoming longer as we descend in the cervical and the thoracic spine, or the body of the vertebrae has different shapes in each section, or the presence of the transverse foramen in the cervical spine, which allow the passage of a nerve plexus, an artery, and a vein. Each section, with its characteristics, aligns to form the vertebrae column containing and protecting the spinal cord.
