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.
The groups of atoms that are used to make unit cells are called monomers. For some plastics, such as polyethylene, the repeat unit can be just one carbon atom and two hydrogen atoms. For other plastics, such as nylons, the repeat unit can involve 38 or more atoms.
