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:
The correct option will be option C.
Explanation:
2,4-Dinitrophenol or DNP is a protonophore molecule which can leak the protons and leads to affect the production of ATP in the mitochondria.
DNP is the best agent known for uncoupling the oxidative phosphorylation as it uncouples the phosphorylation of adenosine diphosphate (ADP) from ATP synthase. It leads to the low production of the ATP during oxidative phosphorylation and most of the energy is converted to heat. It does not effect the electron transport chain, it continues.
Thus, option C is the correct answer.
Answer:
1) vacuole= ur school canteen (if u hve one)
2) chloroplast = ur science teachers
3) lysosomes= ur MATH TEACHER!!!!!!!!! lol
4)NUCLEUS=UR PRINCIPAL'S OFFICE
5)Golgi body = ur school bus
6) cell wall= guards at ur school
If a researcher electrically stimulates the reticular formation in an animal, the animal will immediately wake up and be alert. Its purpose is to have some control of sensory signals and thus has the ability to alert the body when it is tired or needs to be awake.
