Answer:
Replace the concentration descriptions with actual values.
Explanation:
A graph is used to convey real, accurate and objective information. The use of the description of the concentrations in place of the real values, does not represent an accurate information, but a subjective and imprecise information. For this reason, to improve the quality of this graph and allow the readers to fully understand it, it would be necessary to replace the descriptions of concentration with real values.
The answer is the first E. Hope this helps! :D
This phenomenon is referred as Codominance. Codominance is termed as, the distinct expression of both alleles of a gene.
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.
