a. B lymphocytes.

b. neutrophils.

c. monocytes.

d. T lymphocytes.

e. macrophages.

2.Mark is tasked with discovering a microbe capable of degrading acid mine drainage. Which of the following is the process he should use?

nitrogen fixation

quorum sensing

enrichment culture

chemostat

cell culture

Answer 1

Immune response comprises of two arms: Innate or non-specific immune response and adaptive or specific immune response.

Innate immune system acts as a non-specific and is the first line of defense against infection. Adaptive response act against pathogens or infectious agent specifically by various mechanisms including producing specific antibody against pathogens. B lymphocytes (or B cells) secrets antibody into the bloodstream that recognizes and neutralizes antigen (pathogen).

To discover the microbe that has the ability to degrade acid mine drainage an enrichment culture should be used. Enrichment culture allows the growth of particular microbes in response to a particular growth condition or growth media.
