1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's
Answer: The answer is B- Diffusion of calcium ions through NMDA receptors.
Explanation:
Phantom limb pain (PLP) is a painful sensation experienced after the loss or amputation of a limb. The limb is no longer there but the individual can still feel real and severe pains in the limb. This occurs soon after surgery.
NMDA is a receptor for Glutamate which is an excitatory neurotransmitter. The activation of NMDA receptors are associated with hyperalgesia which is an abnormally heightened sensitivity to pain.
The best answer would be:
A. DNA is being transcribed into mRNA.
If you'd like to know why:
In the image shown, you can see the <u>BLUE </u>strands and the <u>RED </u>strand. The Blue strand is DNA and the Red strand is mRNA. What is happening in the picture is TRANSCRIPTION. It is the process of making an RNA copy of the DNA strand to create proteins based on the DNA strand.
The <u>GREEN</u> blob is most likely RNA polymerase. Its job is to synthesize or make a complementary RNA strand of the DNA by assembling nucleotides to form an RNA strand based on the DNA template.
