Answer:

Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves. Scientists in now report that help might be on the way from an unexpected quarter.

Nerve Cells Do Not Renew Themselves After an injury, the skin makes a bunch of new cells and uses them to heal your wound. Yet, nerve cells in your brain, also called neurons, do not renew themselves. They do not divide at all. ... When there is a glitch in the blood supply to the brain, also called a stroke, neurons die.

Explanation:

The G₀ phase describes a cellular state outside of the replicative cell cycle.

What modifies and transports proteins?

Alexandra [31]

<u>Answer:</u> The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER. It is also involved in the transport of lipids around the cell. Pieces of the Golgi membrane pinch off to form vesicles that transport molecules around the cell.
