D. None of the above
Explanation:
All the given options shows the differences between DNA and RNA. DNA is deoxyribonucleic acid whereas RNA is ribonuceic acid.
Both DNA and RNA carries genetic information and they help to store them. There are glaring differences between them:
- DNA is double stranded made up of a twist in a helical structure but RNA is single stranded.
- DNA nitrogenous bases occurs as base pairs jointed using hydrogen bonds whereas we have single nucleobase in RNA.

The Gulf Stream is part of the North Atlantic Subtropical Gyre. The ocean is constantly in motion, moving water from place to place via currents. The Gulf Stream brings warm water from the Gulf of Mexico all the way up to the Norwegian Sea.
Firstly species around the world are constantly dying, therefore having an exact number is impossible. Also there are countless may species that haven’t been identified or died before we could even identify them. But to answer you question you would have 2 more species if you added 2 more to the collection.
Answer:
1. Sorting. The simplest way to separate mechanical mixtures is by sorting.
2. Floating. Sometimes, parts of a mechanical mixture will float on the surface.
3. Settling. Sand and cocoa powder both settle in water.
4. Using a Magnet. Some metals such as iron and steel are attracted to magnets.
5. Using Sieves and Filters.
6. Dissolving.
Explanation:
Mixtures can be separated using a variety of techniques.
Chromatography involves solvent separation on a solid medium.
Distillation takes advantage of differences in boiling points.
Evaporation removes a liquid from a solution to leave a solid material.
Filtration separates solids of different sizes.
