Abnormally slow depolarization of the ventricles would most change the shape of the QRS complex in an ECG tracing.
- The conduction system in the ventricles depolarizes, and this depolarization spreads along the walls of the ventricles to produce the QRS complex.
- It represents electrical activity that occurs before the ventricles contract (ventricular systole). The QRS complex appears immediately after the onset of ventricular systole.
- An aberrant depolarization of the ventricles results in the formation of an abnormal QRS complex.
- The SA node, an ectopic pacemaker in the atria, AV junction, bundle branches, Purkinje network, or the ventricular myocardium are all possible pacemaker sites in these aberrant QRS complexes.
- An aberrant QRS complex might have any shape, from normal to wide and odd to slurred and notched.

<span>They are composed of similar materials: DNA is a deoxyribonucleotide polymer while RNA is a ribonucleotide polymer. A nucleotide is composed of a nitrogenous base, a sugar, and a phosphate group. In ribonucleotides, the sugar is ribose, while in deoxynucleotides, the sugar is deoxyribose. Adenine, guanine, and cytosine are nitrogenous bases in both DNA and RNA, while thymine is found only in DNA and uracil is found only in RNA.</span>

Hello
D. Animal is is the answer.
Hope this helps u!
Let me know if it's correct.
For a fish to be buoyant, or float, it must displace less water or the same amount of water as its own body mass. ... Many fish use swim bladders to help them with quick depth changes. These bladders fill with air to help fish rise or release air so fish can sink, often in conjunction with forward movement.
