Answer:
The function of DNA is tied to its structure. ... When two strands of DNA come together, base pairs form between the nucleotides of each strand. Nitrogenous bases pair together in the following way: A-T and C-G. Bases interact through weak bonds, called hydrogen bonds, that can be easily broken and reformed.
Explanation:
A-T G-C A-T G-C

I just took the test hope this helps.
Answer:
E
Explanation:
Hardy-Weinberg principle states that frequency of alelle and genotype will remain constant in the absence of genetic disturbances such as mutation, no change in the DNA sequence, the population must be large and others
the principle is defined by the equation
p² + 2pq + q² = 1
where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq
substitute the value into the expression
p² + 0.04 + q² = 1; The information is not enough to calculate either p or q going by the equation generated.
The period during which the presence of stromatolites decline is the Proterzoic period. Stromatolites are widely distributed sedimentary structures consisting of laminated carbonate or silicate rocks, produced over geologic time by the trapping, binding, or the precipitating of sediment by groups of microorganisms, primarily cyanobacteria.
