The answer is geological; biological diversity evidence. His hypothesis clarifies that natural assorted qualities come about because of the relatives of nearby or transient ancestors getting to be noticeably adjusted to their differing surroundings. This clarification can be tried by looking at present species and nearby fossils to see whether they have comparable structures, which would show how one is gotten from the other.
Answer:
A periodic law is when there is a stating/table of elements listed in order with their numbers, (atomic numbers/weight) and fall into certain groups with similar elements.
"Contaminated hospital equipment represents a difficult environment to control harmful microbial growth. Regarding influences that affect disinfection of hospital equipment, which of the following is an accurate statement?
- Biofilms, often found contaminating hospital equipment, are relatively simple targets for biocides to reach effectively.
- The presence of organic matter, such as dried blood or protein, will not affect the action of antimicrobial agents.
- Antimicrobial agents work best under reduced temperatures.
- The cell walls of gram-negative bacteria are especially resistant to many chemical that are used to destroy microbes.
"
Biofilms are extracellular matrix formed by organisms. They are slimy and are used to attach to surfaces. They are made of polysachharides and form a barrier of protection against disinfectants. Therefore, they make it difficult to decontaminate surfaces.
Organic matter like dried blood or protein also affect the action of antimicrobial agents. Organic matter may form a layer that would reduce the access of the disinfection to the organism.
Antimicrobial agents are affected by temperature and have optimum temperature of action. Some get denatured by heat while some are unaffected. The temperature an antibiotic works will also depend on the organism and its mode of action.
Gram negative bacteria have shown resistance to more antimicrobials.
