what is the hardware engineering​

Though the microbes described in the introductory chapter do not corrode the metal in the subway, many microbes influence corrosion and deterioration of metal and stone. Other microbes have other effects on their environment. During wastewater treatment, bacteria are used to reduce the amount of organic and inorganic materials so that the water no longer supports substantial microbial growth. During secondary wastewater treatment, bacteria within sludge digesters break down organic materials into fatty acids, H2, and CO2. These products are fermented to acetate, CO2, and H2. Finally, archaeans ferment acetate to form methane and carbon dioxide. Just by knowing this information, what is true of the bacteria used in sludge digesters?a. They are capable of anaerobic metabolism.b. They are sulfate-reducing bacteria.c. Some are methanogens.d. They are capable of forming slime layers. different between density and realative density PLEASE HELP!!What is the length of segment DF A system of equations is graphed on the coordinate plane.y=2x4y=2x+4What is the solution to the system of equations?
