Epigenetic is the study in the field of genetics of cellular and physiological phenotypic trait variations that are caused by external or environmental factors that switch genes on and of and affects how cells read genes instead of being caused by changes in the DNA sequence. Therefore, hence epigenetic research seeks to describe dynamic alterations in the transcriptional potential of a cell.

D. Genes. They have genetic material that determine our characteristics.
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light and this allows electron microscopes to produce higher-resolution images than standard light microscopes.
Answer:
Low validity and low reliability.
