I. treating the substance with nucleases that destroy all nucleic acids and then determining whether it is still infectious
Explanation:
Analysis of the nature of the specimen like the infectious agents (bacterium, virus, viriod, or prion) is very important to diagnose the diseases caused by them, investigate disease outbreak, to determine the clinical course of the infectious disease etc.
There are many methods like direct detection, cultivation assays, serological assays to detect the pathogen type.
Molecular techniques like polymerase chain reaction (PCR) is done to further analyze or investigate the pathogen, like its microbial genome, the virulence factor etc. These are amplification methods which help to investigate the pathogenesis and disease progression. PCR method involves denaturing the DNA polymerase which is a nuclease type of enzyme. Nucleases are present with exonucleases and endonucleases, both of which acts at specific points on the DNA of the pathogen and will create new templates .
Answer: The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. Helping them along the way are the pancreas, gall bladder and liver.

Answer:
In pharmacology, the term mechanism of action (MOA) refers to the specific biochemical interaction through which a drug substance produces its pharmacological effect. A mechanism of action usually includes mention of the specific molecular targets to which the drug binds, such as an enzyme or receptor.
The carrying capacity is impacted by both biotic and abiotic processes. The carrying capacity develops as these conditions improve. The carrying capacity decreases as the factors grow scarcer. When resources are depleted faster than they are replaced, the species has reached its carrying capacity.
<h3>What is carrying capacity?</h3>
The average population size of a species in a given habitat is referred to as carrying capacity.
Environmental considerations such as appropriate food, shelter, water, and mates limit the species population size.
The carrying capacity is impacted by both biotic and abiotic processes. The carrying capacity develops as these conditions improve.
The carrying capacity decreases as the factors grow scarcer. When resources are depleted faster than they are replaced, the species has reached its carrying capacity.
Thus, in this way abiotic factors and biotic factors affect population growth.
