The islets of Langerhans, which are regions of the pancreas, so D.
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.
All of the following contributes to turbulent blood flow except third and fourth heart sounds.
<h3><u>
Explanation:</u></h3>
The blood flow in human body is always described to be laminar. Some conditions cause the high flow when there is an ascending aorta. This causes the laminar flow of blood into turbulent. When this occurs the flow of the blood will not be smooth and linear.
When the kinetic energy in the fluid flow increases the turbulent flow of blood occurs. Both the magnitude and the direction of the flow changes in this type of blood flow. These are caused by the irregularities in the vessel walls, flow rates to ne higher and opening of the valves of the heart.
