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.

Answer:
transcription is the synthesis of an mRNA molecule using a DNA molecule for a template. That mRNA molecule then goes on to complete translation in the ribosome. Translation is the process in which proteins are produced based on instructions carried by mRNA.

Answer:
the speed of the ball remains the same.
Explanation:
due to newtons law of what goes up must come down applys to this question, and therefore the speed doesn't change.
