Answer:

The order from least susceptible towards more susceptible is

prions

endospores

Gram-negative bacteria

Grampositive bacteria

enveloped virus

Explanation:

Enveloped virus are most susceptible because it's enveloped is made up of lipid which can easily be degraded by disinfectants after which the virus can be killed easily.

Gram-positive bacterial cell wall is made up of the only peptidoglycan and gram-negative cell wall is made up of two-layer peptidoglycan and lipopolysaccharide. So gram-negative bacteria have more protection therefore gram-positive bacteria are more susceptible than gram-negative.

An endospore is one of the least most susceptible form which is formed by members of two genus bacillus and clostridium. It is formed outside the cell and protects bacteria from disinfectants and other environmental resistance.

Prions are the least susceptible form of pathogen because they are non-living. Prions do not have genetic material and they are misfolded proteins. So antimicrobials do not work on prions.  

Therefore the correct order from least susceptible towards most susceptible is-  

prions

endospores

Gram-negative bacteria

Grampositive bacteria

enveloped virus

What would be the advantages of using “natural regeneration” over stem cell transplants?
Serhud [2]
In the science world today, both the natural regeneration and stem cell therapy can be used to generate new cells and both processes have thier advantages and disadvantages. The following are the advantages of natural regeneration over stem cell transplants:
1. Natural regeneration is cheaper compares to stem cell transplant.
2. The process of natural regeneration is safe and does not involve the fear of unknown, long time effects like that of stem cell transplant.
3. Naturally regenerated cells can not be rejected by the patient's body but a stem cell transplanted cell can be rejected by the patient's body.

Animals in the chaparral biome are not especially vulnerable to drought. Please select the best answer from the choices provided
Marina CMI [18]

Answer;

The above statement is true

Explanation;

Some of the adaptations of the chaparral fauna are that the animals do not require much water. The animals have learned to live in their biome by being nocturnal and are usually small. The animals are all mainly grassland and desert types adapted to hot, dry weather.

Organisms that live in the chaparral have developed unique adaptations that aid in their survival. Coyote brush is a unique plant found in the chaparral of California and Oregon. The shape a coyote brush takes depends on the location in which it is growing, but each coyote brush plant develops a large root system that extends outward many yards from the main plan
