Microbes that thrive in acidic environments seem to have "cost free" ATP energy available to them due to the pre-existing H grad
bixtya [17]

Answer:

The microbes thriving in acidic environments are termed as acidophiles, and these range from eukaryotes to bacteria and archaea, which are mainly found in diverse acidic surroundings like sulfuric geysers and pools, in the human stomach, and in the regions that get polluted by acid mine drainage.  

The mentioned case is not entirely correct as the protons found in the acidic surroundings are not utilized for the generation of ATP as they are not originating from within the cell. In order to sustain their internal acidic pH, the acidophiles exhibit adaptations like the presence of the negatively charged proteins on the surfaces of their membranes so that they can prevent deterioration due to acidic surroundings.

the first cells likely to encounter a pathogen, such as phagocytes, are professional antigen presenting cells (apcs). this means
Zepler [3.9K]

Professional antigen-presenting cells, such as phagocytes, are the first cells to encounter a pathogen (apcs). This means they have the ability to activate cells of the adaptive immune system.

<h3>What is meant by Pathogen?</h3>
  • A pathogen is an organism that infects its host with disease, and the severity of the disease symptoms is referred to as virulence.
  • Pathogens include viruses, bacteria, unicellular and multicellular eukaryotes, and a wide range of other organisms.
  • The bone marrow of an average healthy adult generates 100 billion new neutrophils per day. Because there are so many neutrophils in the body at any given time, they are often the first cells to reach the site of an infection.
  • Long thought to be a component of the innate immune system, complement has recently emerged as an important regulator of the adaptive immune response.

Therefore the correct option is D)  can activate cells of the adaptive immune system.
