Q: What molecules with a nitrogen base are the basic components of nucleic acids? Read this paragraph and choose the correct option from the provided answers: The basic components of nucleic acids are nucleotides. A nucleotide is a molecule that contains a five-carbon sugar, a phosphate group, and a nitrogen containing base. The five-carbon sugar is either ribose, in the case of RNA, or deoxyribose, in the case of DNA. The only difference between the two molecules is the presence of a hydroxyl group attached to one member of the carbon ring in RNA. In DNA, that same carbon atom is attached only to a hydrogen atom (see Figure below ). Note that in drawing the structure of organic molecules, the single hydrogen atoms are not shown in the structure but are understood to be attached at each carbon point unless another molecule is shown. Choices: - sporozoans - enzymes - nuclides - nucleiotides A:
**Answer**
nucleiotides

Read this paragraph and choose the correct option from the provided answers: Cytoplasm refers to all of the cellular material inside the plasma membrane. Cytoplasm is made up of a watery substance called cytosol and contains other cell structures such as ribosomes. Choices: - rna - plasma - cytoskeleton - cytoplasm A:
**Answer**
cytoplasm

Q: What is the name for the sinking of the dense, salty seawater in cold climates? Read this paragraph and choose the correct option from the provided answers: Water becomes more dense when it is colder and when it has more salt. In the North Atlantic Ocean, cold winds chill the water at the surface. Sea ice grows in this cold water, but ice is created from fresh water. The salt is left behind in the seawater. This cold, salty water is very dense, so it sinks to the bottom of the North Atlantic. Downwelling can take place in other places where surface water becomes very dense (see Figure below ). Choices: - cyclones - jet stream - tidal activity - downwelling A:
**Answer**
downwelling
