Answer:
We are all familiar with the basics of viruses: These particles infect living cells and wreak havoc throughout the body. But viruses aren’t the only villains around causing chaos in living things. Other infectious agents called viroids and prions — which are also tiny but powerful — can take down both plant life and entire animals.
Viroids are free RNA molecules of low molecular weight without any protein coat, while viruses can have either RNA or DNA molecules encapsulated in a protein coat. Viroids are smaller in size than viruses.
Viroids not made of cells.
Viroids don’t transform energy.
Viroids can’t reproduce on their own.
I would think the biological information passed from generation to generation is called “DNA”.
Some microorganisms such as yeast produce energy in oxygen-free environments through anaerobic cellular respiration. Anaerobic cellular respiration is where oxygen is not used. Yeast produces energy by converting sugars into alcohol, gas or acetic acid. <span>This process is called fermentation. </span>Ethanol is a by-product of fermentation. Humans have used fermentation to produce food and drink since the Neolithic Age. Fermentation makes yoghurt from milk by producing lactic acid. It also produces alcoholic beverages such as wine from grapes.
