Answer:
it is ur spine
The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system. In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm in men and around 43 cm long in women. The diameter of the spinal cord ranges from 13 mm in the cervical and lumbar regions to 6.4 mm in the thoracic area.

Answer:
Cardiorespiratory endurance tests monitor how well the heart, lungs, and muscles perform during moderate to high-intensity exercise. Increasing cardiorespiratory endurance improves oxygen uptake in the lungs and heart and can help a person sustain physical activity for longer.Explanation:

Answer:
B) the long term dangers of using the drugs are not yet understood.
Explanation:
Because these drugs have just started being created, scientists can not know for certain what these effects these drugs will have on the body 30, 20, or even 10 years after consumption.
Answer:
Diplopia
Explanation:
Diplopia, also called double vision, happens when the eyes are not aligned correctly, transmitting images of the same object to the brain, but from different angles. People with diplopia cannot fuse images from both eyes into a single image, creating the sensation that two objects are being seen instead of one; or they need to point their eyes inward to focus on an object.
Of all the vision disorders, diplopia is perhaps one of the most troublesome - and identifying its cause is a challenge. Diplopia happens when the eyes have a discrepancy between them and send images of the same object to the brain from different angles, so that it cannot understand them as the same and cannot merge them into one, causing vision double.
