Answer:
Epigenetic phenomena
Explanation:
Epigenetics involves the changes in gene expression which is not as a result of changes in an individual's DNA sequence. In other words, it is a change in an individual's phenotype, without an alteration in the genotype.
It is involved in the normal functioning of cellular processes.
Examples of epigenetics is DNA methylation ( adding of a methyl group to a section of the DNA molecule) and histone modification such as histone acetylation (adding an acetyl group to the histone).
Epigenetic changes can switch off genes, hence, prevent the expression of those genes; it can also turn on genes, hence increase the expression of those genes.
Epigenetic changes can also results to diseases such as cancer.
Answer:
A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.

Explanation:
Compounds are those substances that are made up of elements that are combined in a fixed proportion or ratio. The individual property of element is lost once it forms a compound. The physical and chemical properties of both compound and an element is different.
Example of a compound is water and its elements are hydrogen and oxygen. Water is a colorless liquid that acts as a solvent and dissolves most of the solutes in it. While oxygen and hydrogen occurs as gases in their elemental state.
