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.
The statement is - False.
The vinegaroon has became very similar in appearance to the scorpions, by having similar body, similar proportions to certain species, having a whip tail. The whip tail though is not a mimic for the scorpion's pincher claws, but instead, it is a mimic of the scorpion's stinger. This adaptation of the vinegaroon has the purpose to fend of the predators by making them think that it is actually a scorpion and that they will get a nasty poisonous sting. This type of adaptations by mimicking certain traits of more dangerous species can be found in lot of animals from all shapes and sizes.
