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.

The difference in concentration between solutions on either side of a cell membrane is?
The difference in concentration between solutions on either side of a cell membrane is a concentration gradient.
In the field of biology, a concentration gradient can be described as a difference in the concentration of molecules inside and outside of a cell. It is due to concentration gradient that molecules move into and out of a cell through the cell membrane.
Some molecules move from an area of higher concentration gradient to an area of lower concentration along the concentration gradient. Diffusion is an example of such a process.
On the other hand, some molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Active transport is an example of such a process.

d. localized hypoxia.
Cell damage may be caused by exogenous sources such as abnormal metabolic processes. So the correct option is A.
What is cell damage?If enough cells are destroyed as a result of toxic damage to cells, there may be tissue or organ failure, which eventually results in organism death. Discussions of cellular toxicity and biochemical toxicity are essentially inseparable.
The majority of detectable cellular alterations and cell death are brought on by certain biochemical alterations either inside the cell or in the tissue around it. There are, however, a few circumstances in which a harmful chemical or physical substance might harm cells without actually altering any particular chemicals present in the cell or its membrane.
Physically damaging substances like heat and radiation can harm a cell by coagulating its contents (similar to cooking). There are no particular chemical reactions in this situation. A cell may be deprived of vital supplies necessary for existence due to a compromised food supply (such as oxygen and glucose).

It's a chocolate-based introduction to the rock cycle!
Like rocks, chocolate can be squeezed, heated, cooled, and weathered into tiny particles. Chocolate can go through these processes safely and at normal temperatures, unlike rocks.
Create "sedimentary," "metamorphic," and "igneous" chocolate using your supply of chocolate. Make a wonderful treat at the end of it all!
Materials:
Blocks of white and dark chocolate Cupcake liners made of aluminum foila container to hold the hot watera plastic knife or another straightforward scraperMaking "sedimentary" chocolate first:
1. Scrape a few tiny pieces of chocolate from your blocks.
2. Place all of these scrapings on a piece of aluminum foil and push down. You could press the chocolate shavings onto the aluminum foil after folding it. You may even stand on foil packets that were sealed.
3. Note how the consolidated group of chocolate scrapings in the foil now resembles sedimentary rock.
Make "metamorphic" chocolate next:
1. Fill some aluminum foil or a cupcake holder with a small pile of your sedimentary chocolate, possibly some of your original unused scrapings, and a few small chunks from your initial blocks.
2. Float this mixture in water that is moderately heated.
3. Keep an eye on the foil and chocolate as they begin to melt when the heat from the water is transferred to them.
4. When the chocolate feels soft to the touch, remove the foil (for safety, use the plastic knife, not the fingers).
5. Allow the chocolate to cool. The chocolate has now chilled and only half melted, resembling metamorphic rock.
Make "igneous" chocolate next:
1. Fill your aluminum foil or cupcake holder with a tiny mound of sedimentary and metamorphic chocolate and a few pieces from the initial blocks.
2. Float this mixture in extremely hot water.
3. Observe how the heat from the water is transferred to the foil and melting chocolate. The chocolate should be allowed to melt until smooth liquid forms.
4. Carefully remove the melted chocolate from the aluminum container and let it cool. Now that your chocolate has melted and cooled, it resembles volcanic rock.

Metallic luster, which is extremely reflective and opaque, to dull luster (non-reflective and opaque.)
Mineralogists use the physical characteristic of luster to identify minerals. A mineral's luster defines how its exterior reflects light and how its inside may bend or refract light. Some minerals have a metallic sheen, while others don't.

In patients with low platelet counts or functional platelet disorders, platelet transfusion is a life-saving procedure used to stop ongoing bleeding or stop potential bleeding.
