Question 5 2 pts Based on disease models, vaccination can control diseases by Killing infected hosts Reducing the number of susceptible hosts in a population Reducing host death rates Reducing pathogen virulence All of these Question 6 2 pts Community ecology is best defined as the study of plant distributions in a given region. mutual benefits between organisms at all scales in a region. the relationship between abiotic and biotic factors. how groups of species interact in the same place at the same time. global scale influences of major disturbances such as volcanos.

Answer 1

Ans. 5. Vaccines help to develop infection. Vaccines trigger that the next time the pathogen, it can fight immunity by imitating an antibody production, so body encounters the it off matters number of susceptible option hosts and i.e. in a reducing the population .. herd GOLDY Susceptible person or unvaccinated personi get protection thorough vaccination Also targeted vaccination help in source drying. . Vaccination do not kill infected hosts, don't reduce host death rate as such . Host death rates are decreased due to the only providing immunity of by decreasing their chance to get infected. ne

Ang 6- Community ecology in best defined as the study of how groups of species interact in the same place at the same time. Community ecology also can be defined as association of populations of two or more species present in same geographical area at some time. ex. Forest community, coral reef community. Community ecology involve all type of interactions like mutualism, commensalism, predaction etc. Relationship between bistic and abiotic factors comes under ecosystem.
