Answer and Explanation:
This happened because when the agar was desiccated, all the water was released, but the solutes used in the culture medium remained in the petri dish, that is, all the nutrients remained available to H. salinarium, which survived by consuming these nutrients. Although the growth of H. salinarium requires a higher level of NaCl than the level left in the petri dish, we can consider that some colonies of H. salinarium adapted to the low level of NaCl and managed to survive, passing this characteristic to new colonies.
The Calvin cycle is called the dark cycle because it does not require
light to proceed. Unlike light reactions, the Calvin cycle is a
light-independent reaction, which means it can and will occur in the
dark as well as the light. The Calvin cycle is called the dark cycle
because it does not require light to proceed.
hope this helps :p
