Answer:
signaling processes
Explanation:
Neurons within the brain are constantly processing and transmitting information. Electrical impulses that pass from one neuron to another consume a lot of energy. So, sending, receiving and processing the signals are the main events of brain energy expenditure. Neurons also use the energy for the maintenance of themselves and the surrounding glial cells.

Binary fission
Explanation:
Prokaryotic cells do not have a nucleus. Binary fission is one of the methods of asexual reproduction in them. During the process, replication of circular DNA begins at the origin of replication and continues as the replication is bidirectional and the enzymes synthesize DNA in both directions.
As the replication comes to an end, the cell appear to have two circular DNA molecules entangled with each other. The septum grows towards the inner side as the chromosomes move toward opposite ends of the cell. This is followed by the formation of septum completely through the cell center, to make two separate cell chambers.
