Answer:
Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.
While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood.
Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.
Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

Hippocrates was a Greek physician, he is well known for the discovery of the medicines, which were based on the scientific observation. He is also known as virtual originator of the etiology and the pathology.
Hippocrates suggested that the body can remain disease free, or the chances of being diseased can be diminished, if good diet, fresh air, cleanliness and exercise are maintained.
Hence, four things, which help body to heal itself, according to Hippocrates are:
- Good diet
- Cleanliness
- Exercise
- Fresh air
<h2>Epigenetic modification </h2>
Explanation:
A methyl group bound to DNA inhibits transcription of a gene describes an epigenetic modification
Epigenetic modifications include: histone modifications and methylation
Methylation is the main cause of gene silencing for example methylation at lysine residue of histone protein, H4 leads to gene repression
Small silencing RNA molecules are of two types: micro RNA (miRNA) and small interfering RNA (siRNA)
miRNA directs degradation of target mRNA when makes perfect complementary while suppress mRNA translation when makes partial or imperfect complementary
siRNA primarily mediates degradation of target RNA
