A. A stress test can be used to test for heart disease. Stress tests are tests performed by a doctor and/or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle).
(1pt) There are four different variations of these monomers (four different nucleotide bases), what are the names of those bases? They are Adenine (A), Thymine (T), Guanine (G), Cytosine (C). 5. (1pt) These bases specifically pair with one other base, known as complementary base pairing.
Monosubstituted monomers, on the other hand, may join together in two organized ways, described in the following diagram, or in a third random manner. Most monomers of this kind, including propylene, vinyl chloride, styrene, acrylonitrile and acrylic esters, prefer to join in a head-to-tail fashion, with some randomness occurring from time to time. The reasons for this regioselectivity will be discussed in the synthetic methods section.
