Although hospice and palliative care share the same principles of providing comfort and support for patients, palliative care is available throughout a patientâs experience with cancer, whereas hospice is offered only toward the end of life.
The process used by some protists to actively ingest food particles is called Phagocytosis.ther protists like fungus grow  above their food source to get nutrients. Some protists engulf  bacteria and digest them internally, by extending their cell  membrane and forming a vacuole around the bacteria.
When an energy substrate is available, often a simple carbohydrate, and often under anaerobic (lack of oxygen) conditions, fermentation will proceed. Many microorganisms use fermentation as an energy producing pathway. These may include molds, fungi, and bacteria. No, food can not ferment on its own. Fermentation is always a biological process. We often think of food spoilage or fermentation as being spontaneous. But this is due to the fact that we can not see the very small (micro) organisms doing the activity.
