Answer:
Herd immunity
Explanation:
Herd immunity refers to the resistance of a group of people against infection and the spread of a pathogen. It occurs when a high proportion of the members of that group are resistant against a particular pathogenic infection. When an earlier exposure or vaccination of a large proportion of individuals of a population does not allow the pathogen to spread among and infect the otherwise susceptible members of the population, the population is said to have acquired the herd immunity.
In the given example, vaccination of a large percentage of a population protected the susceptible individuals against a particular microbe. This represents an example of herd immunity.
B is the answer because it the ER helps with protein transport.
Answer:
C) phenotypic plasticity
Explanation:
- The ability of an organism to change phenotypically according to environmental conditions is known as <u>Phenotypic plasticity</u>.
Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.
Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.
- Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are <u><em>metabolically versatile</em></u><u><em>. </em></u>They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.
These bacteria are <u>notoriously adaptable</u> and <u>might be found in many different environments</u> (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.
<em>They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine</em>.
