those are nucleotides
since all three of them contain deoxyribose (because there's only one hydroxil group) they are DNA nucleotides
the first nucleotide has cytosine as it's nitrogenous base
the second nucleotide has adenine as it's nitrogenous base
the third nucleotide has thymine as it's nitrogenous base
The main difference between inductive and deductive reasoning is that when we're doing inductive reasoning we're trying to create formal rules or formal inferences from a limited set of information, while during deductive reasoning, we're trying to deduce what would happen in a certain case based on general information available.
X - linked traits appear more often in males because males only have one x chromosome. One copy of an x - linked trait is all that a male would need to possess that trait. Females have two x chromosomes, so they would require 2 copies of the x - linked trait in order to possess it.
