Tachycardia is a condition when the heart rate is greater than 100 beats per min at rest. The electrocardiogram is a diagnostic tool that measures and records the electrical activity of the heart. Bradycardia on the other hand is when the heart rate is slower than normal. The Tachycardia and bradycardia can arise from either the SA node or from other areas of the cardiac.

Answer:
__ It implies that prokaryotes existed before eukaryotes, and
__ It implies that eukaryotes evolved from prokaryotes.
Explanation:
The prefix pro- can mean "before". By using the term prokaryote one can tend to think that procaryotes preceded eukaryotes.
Preceed as existed before them, or as an evolutionary point of view.

The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.
Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.
Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.
Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.
