Elena L [17]

ANSWER: The origin of the pain is from the intervertebral disks of the lumbosacral spine.

EXPLANATION:

Sciatica is pain in the lower extremity resulting from irritation of the sciatic nerve.

The sciatic nerve is the largest nerve in the body and begins from nerve roots in the lumbar spinal cord in the low back and extends through the buttock area to send nerve endings down the lower limb.

Sciatica is caused by irritation of the root(s) of the lower lumbar and lumbosacral spine. Additional common causes of sciatica include: Lumbar spinal stenosis (narrowing of the spinal canal in the lower back) Degenerative disc disease (breakdown of discs, which act as cushions between the vertebrae).

The nitrogen cycle is most directly dependent upon-
vovangra [49]

Answer:

B) Nitrogen-fixing bacteria and lightning

Explanation:

Nitrogen cycle is the natural process in which atmospheric nitrogen is converted into nitrite and nitrate with the help of bacteria.

Nitrogen cycle is directly dependent on nitrogen-fixing bacteria and lightning.

As bacteria are responsible for most of the chemical conversion in the nitrogen cycle such as nitrogen fixation (first step) is done by soil bacteria (Cyanobacteria) that form ammonia, which is toxic to plants; nitrification in which ammonia is converted into nitrites and nitrates with the help of Nitrobacter and denitrification bacteria involve Pseudomonas, and Achromobacter which convert nitrite and nitrate into nitrogen.

The lightning breaks nitrogen molecules and allow  it to combine with oxygen in atmosphere which further dissolve in rain and form nitrates.

Hence, the nitrogen cycle is most directly dependent upon nitrogen-fixing bacteria and lightning and the correct option is B.
