Answer:
only sympathetic fibers can regenerate accurately
Explanation:
Neuroregeneration is a complex biological process associated with the regrowth and/or repair of nervous tissues. This process depends on the type of nerve tissue and how seriously the nerve was injured. The autonomic nervous system, also known as the autonomic nervous system (ANS), is part of the peripheral nervous system (PNS) that is responsible for regulating involuntary physiological processes. The PNS contains two basic divisions: sympathetic and parasympathetic. The sympathetic fibers innervate tissues in nearly all the organ systems and they are responsible for regulating homeostatic processes (e.g., heart rate). The sympathetic nervous system is formed by nerves from the thoracic and lumbar segments of the spinal cord. These autonomic nerves can regenerate after injury in order to reinnervate target tissues (e.g., after chronic cardiac ischemia).

1) true; 2) false; 3) true
Answer:
Correct choice should be:
"SGSG"
Explanation:
The cell cycle consists of G1, S, G2 and M phase. The former three phases include the interphase and M phase is the dividing phase of cell . G1 prepares cell for DNA synthesis. S phase is the phase where DNA replication takes place. G2 phase prepares cell for cell division or M phase.
G1 phase preceeds replication or S phase and G1 phase licences DNA replication.
During other phases of cell cycle, ORC complex masks origin of replication. ORC phosphorylation takes place at S phase, which removes this omplex and unmasks origin of repication site so that replication machinery can bind to it.
DNA helicase activation: S phase
DNA helicase deposition on DNA at the replication origins: G phase (actually G1)
ORC phosphorylation: S phase
Licensing of replication origins : G phase (actually G1)
Hence correct choice should be:
SGSG
