Answer:
The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".
Explanation:
Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.
It depends on where the fuel source is coming from and also how much fuel is there.
When testing diffusion over a selectively permeable membrane, the proper setup is aimed at putting different concentrations into tubes and the same water volume.
<h3>What is a selectively permeable membrane?</h3>
A selectively permeable membrane is a physical barrier that allows the passage of certain substances but not others.
The cell membrane is a selectively permeable membrane that cells need to interchange nutrients and waste with their environment.
In conclusion, a suitable experiment to show the process of diffusion in a selectively permeable membrane is to put concentrations of the solute into tubes and the same volume of solvent (water).
