Answer:
1) Hydrogen
2) Nucleotide phosphates
3) Sugar
4) Original free DNA
5) Unzip exposed bases
6) Identical
7) New
8) Complementary
Explanation:
2 Choose from the following words to fill in the blanks of the steps in DNA replication. Each one may be used only once. identical new sugar unzip exposed bases original free DNA nucleotides phosphate hydrogen The ____hydrogen_ bonds between the bases break, and the two DNA strands unwind and____ nucleotides phosphates____ are brought in, and they attach to the ____sugar___ on both DNA strands. Bonds form between the ___original free DNA___ and ____unzip exposed bases__ molecules of the just-arrived DNA nucleotides, forming a new strand. DNA replication results in two DNA double helices, each composed of one ___identical___ and one ___new__ strand. The new DNA molecules are ____complementary_____ to each other and the original DNA.
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).
Malthus didn't account for diseases or natural disasters in his theory of population growth.
Active transport require the cell to expand energy whilst Passive transport require no energy from the cell in active transport.
Passive Transport moves molecules across membrane without the use of energy by the cell.
-Simple diffusion
-Facilitated diffusion
-Osmosis
Active Transport uses energy (ATP) to move molecules across membrane.
-Protein pumps
-Exocytosis
-Endocytosis (Phagocytosis & Pinocytosis)
