So Global warming is the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere.
Climate change is the increasing changes in the measures of climate over a long period of time.
This includes : precipitation, temperature, and wind patterns.
Hopes this helps :)
D. The discoveries confirmed many but not all of the classifications that were based on observable traits, and scientists revised classifications when necessary.
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.
