Answer the following question given this paragraph: It was known that DNA is composed of nucleotides , each of which contains a nitrogen-containing base, a five-carbon sugar (deoxyribose), and a phosphate group. In these nucleotides, there is one of the four possible bases: adenine (A), guanine (G), cytosine (C), or thymine (T) ( Figure below ). Adenine and guanine are purine bases, and cytosine and thymine are pyrimidine bases. Q: What does the base of a nucleotide within dna consist of? Choices: - ribosomes - protein - hydrogen - nitrogen A:
(Answer)
nitrogen

Answer the following question given this paragraph: Protozoa can be classified on the basis of how they move. As shown in Table below , protozoa move in three different ways. Only sporozoa cannot move. Note that this classification is based only on differences in movement. It does not represent phylogenetic relationships. Q: Protozoa can be classified on the basis of how they? Choices: - smell - look - feel - move A:
move
