Answer: 31 pairs of spinal nerves
Explanation:
In the nervous system, bundles of fibres are called nerves.
The spinal nerve carries motor, sensory, and autonomic signals/information from the spinal cord to the brain and other part of the body.
The human body spinal cord consists of 4 regions, and 31 pairs of spinal nerves. The 31 pairs of spinal nerve are distributed one on each side of the vertebral column within the four regions of the spinal cord. The four regions of the spine are the cervical, thoracic, lumbar and sacral regions.
Answer is 31 pairs.
Answer:
Carbohydrate = 57.023g
Fats = 20.736g
Proteins = 25.919g
Explanation:
According to this question, Valerie is planning to eat at dinner meal that has a total of 800 Calories.
- 55% calories come from carbohydrate i.e. 55/100 × 800 = 440 calories
- 20% calories come from fat i.e. 20/100 × 800 = 160 calories
- 25% calories come from proteins i.e. 25/100 × 800 = 200 calories
Since 7.716 calories = 1g
1. Amount of carbohydrates in gram = 440/7.716 = 57.023g
2. Amount of fats in gram = 160/7.716 = 20.736g
3. Amount of proteins in gram = 200/7.716 = 25.919g
