Ranking on hormonal levels presents on mutant ob, db and normal rats parabiosed to either.
(db rat +ob rat) ( db rat + normal rat) (ob rat + norma rat )(normal rat + normal rat )

Answer:
It decreases the amount of energy necessary for the reaction to proceed.
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). <span>DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.</span>
