Answer: It helps in the removal of abnormal heart rhythm
Explanation:
The AHA's chain or survival includes many steps in it. This is required to save the life of a person in emergency conditions.
One of the main step in AHA's chain of survival includes Rapid defibrillation which is given to a person after CPR.
This condition eliminated the abnormal cardiac rhythm. Electric shocks are given by the medical team so as to treat the emergency conditions like heart attack, cardiac arrest, et cetera.
Well, there is only one realistic answer. Option One is when you take the DNA of two different people or creatures and combine them into one organism. Cloning wouldn't prove anything here, "hybridization" is weird - but it doesn't have anything to do with the situation. So only only remaining option is DNA Profiling - also known as DNA Mapping, which shows the DNA structure and order that can be seen the same way in siblings (slightly different of course but it is still the right answer).

Answer AND Explanation:
The variations that Darwin regarded as raw materials for the process of evolution have been traced to changes that occur at the gene level or the chromosome and these changes are called mutations. Organisms with beneficial mutations are able to pass them on to their offspring during reproduction. Transmission of such mutations through many generations could lead to the emergence of new species. The emergence of new species requires a long time and is also affected by the rate of mutations that a particular species undergoes. This leads to evolution.
