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.

Analyze and evaluate how natural selection produces change in populations as opposed to individuals.​
RSB [31]

Answer:

Natural selection can be described as a phenomenon in which individuals of a population which are better adapted to survive in an environment are favored by nature as compared to the individuals of the population which lack better characteristics to survive in the environment.

Through natural selection, evolution occurs and the allelic frequency changes over a period of time. The process of evolution as well as change in the allelic frequencies does not occur just by a single individual, rather it is a collective effort which takes a lot of time. Hence, we say that natural selection changes the population and not a single individual.

The wechsler intelligence scale for children (wisc) is a good indicator of innate "genetic" ability for:
goblinko [34]

Answer:

The wechsler intelligence scale for children (WISC) is a good indicator of innate "genetic" ability for children of six to sixteen years old.

Explanation:

Wechsler Intelligence Scale for Children (WISC) is basically a system of testing IQ of children from six to sixteen years old. This testing was created by David Wechsler, who stated that intelligence is a global quality and it should be reflected in children's verbal as well as non-verbal abilities.

This testing system is used by schools for several purposes:


• To evaluate the performance of kids during placement process.  

• It is also used to evaluate abilities of dis-abled children or  deferentially able children.

• IQ scores from WISC can be used to diagnose the problems of the children such as mental re-tardation or some specific learning dis-ability. It can also be used to determine the problems of the children who face hyperactivity or attention deficiency.


• In addition, the test can also diagnose brain related and neuro-psychological disorder.


Point to remember:

The WISC system is not useful to determine the extreme form of intelligence like IQ below 40 and above 160. Wechsler himself focused on this point many times that test is not adequate for children with IQs of below 70 or above 130. Despite of this fact, people use this test to determine the intelligence of deferentially able children who usually have IQ above 130 that is not very appropriate thing.
