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.

The leading cause of limited water supplies is low precipitation. Anything will not be limited until a huge production has been created. Hence, overuse, limiting use, and government are not responsible for the cause of limited water supply.
<h3>What do you mean by Precipitation?</h3>
Precipitation may be defined as any sort of water that originates in the Earth's atmosphere and then falls onto the surface of the Earth. It includes snow, rain, hail, dew, etc.
Precipitation is considered the major component of the water cycle that mediates the transport of water movement across the planet. If it declines, the supply of water gets limited.
Therefore, the leading cause of limited water supplies is low precipitation.

The Hardy-Weinberg principle is used to characterize the distribution of the different genotype frequencies in a population which are not evolving. In the Hardy-Weinberg equation,
the frequency of the homozygous dominant genotype is denoted by 
;
the frequency of the homozygous recessive genotype is denoted by 
;
the frequency of the heterozygous genotype is denoted by 2pq;
the frequency of the recessive allele is denoted by q;
the frequency of the dominant allele is denoted by p.
Answer:
Parasitism
ExplanatioThe flatworm seems to be the only one benefitting from the relationship because it is using the snail as a host and provides it a place to grow but the snail is being harmed by the worm while doing so. Therefore the relationship is parasitic.
Deforestation is one major concern with harvesting wood. There are also all types of organisms that lose their habitats.
