The flow of energy is always one way. If we start at the sun and the sun’s energy moves to a plant, then the plant cannot transfer that energy back into the sun. The flow of energy is always controlled bc there is always a visible path it takes.
Epigenetics is the study of how DNA methylation and alterations to chromosomal proteins affect a gene or group of genes express themselves. For changes in a gene's expression, both of these are need.
In a biological process called DNA methylation, methyl groups are added to the DNA molecule. A DNA segment's activity can be altered by methylation without the sequence changing. DNA methylation usually inhibits transcription of genes when it occurs in a gene promoter.
Epigenetics literally translates to "along with changes in genetic sequence." Any procedure that modifies gene activity without altering DNA sequence and results in modifications that can be passed on to daughter cells is now included in the term. Is called Epigenetics.

Answer:
Explanation:
If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon. Tanner further explained that a scientific theory is the framework for observations and facts.
Answer:
The correct answer is option - A, B, C, and D.
Explanation:
The adaptive immune system is also known as a specific immune system or acquired immune system is an immunization system that is made up of which is clonal as it expands rapidly the Lymphocytes that are T lymphocytes and B lymphocytes. The adaptive immune system also has memory this is the reason vaccination is used so it can generate antibodies and make memory cells. Vaccines induce the production of the immune cells or antibodies so it can be stated that it is inducible.
Thus, the correct answer is option - A, B, C, and D.
