Answer:
DNA is also called deoxyribonucleic acid which is made up of two chains which wind around each other to form a double helix model. The 2 DNA strands are also called polynucleotides and they are made up of monomeric units known as nucleotides. These nucleotides are made up of one of four nitrogen-containing nucleobases: cytosine, guanine, adenine and thymine, a phosphate group, and sugar known as deoxyribose.
Nitrogen bases present on the two separate polynucleotides strands are bound together with the help of base pairing (such as adenine with Thymine) and with hydrogen bonds to form double-stranded DNA.
So, adenine in DNA is complementary to thymine.
Basically all of the choices given are failure of negative feedback mechanisms to maintain homeostasis. The correct option among all the options that are given in the question is the last option or option "E". I hope that this is the answer you were looking for and it has come to your help.
<span>This
type of symbiosis is commensalism. Commensalism is a relationship between two
organisms in which one benefits from the other and the other organism is not affected
in any way. From the question above, in the relationship, microscopic mites are
the commensals as they benefit from their host; humans and humans neither benefit
nor are harmed.</span>
