Answer: The structure of the spinal cord can be described as consisting of all the above named. 
Explanation:The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous extension known as the filum terminale.
It is about 45 cm (18 in) long in men and around 43 cm (17 in) in women, ovoid-shaped, and is enlarged in the cervical and lumbar regions.
 
        
             
        
        
        
Answer: cyclic
Explanation:
This pattern often fits in with daily body rhythms or with the sleep and wake cycle.
For example, Cortisol hormone accumulates early in the day, reduces towards the afternoon, and rises towards the end of sleep and maximizes during the morning hours.
Thyroid stimulating hormone (TSH) rises to the maximum point during sleep and reaches its low point three hours after the individual wakes up.
Growth hormone (GH) levels rise 90 minutes after sleep begins.

All 3 farming techniques are methods of soil conservation. 
Contour plowing is used to stop water from flowing directly down slope to prevent gullying. 
Terracing is used to slow the amount of runoff, and prevents rapid soil erosion. 
Strip Cropping is when farmers plant plants in alternating bands to stop soil erosion.
