C. Agar provides a solid surface for bacterial growth.
Agar is a substance obtained from red algae which when added to a culture media, provides a solid surface for the growth of bacteria. When the agar is not added then the culture media remains as the broth and when the agar is added then the broth gets solidified.
Agar is added 1.5-2% in the broth to get solidified. The growth of the bacteria depends on the amount of agar added. Agar is used for the growth of bacteria because it has gel like properties which holds the nutrients evenly and the bacteria can use it accordingly.
As a substance absorbs heat the particles move faster so the average kinetic energy and therefore the Temperature increases. Temperature is a measurement of the average kinetic energy of the molecules in an object or system.
Electrons in photosystem I are energized by electromagnetic radiation with a wavelength of about 690 nanometers(colour red). These electrons are received from plastocyanin to then be passed on to NADP to form NADPH+.
