<span>Myelination enhances the speed of action potential propagation.
The difference between myelinated and unmyelinated axons are in the propagation of action potential. In unmyelinated axons, the action potential travels continuously through the axons. On the other hand, among the myelinated nerve fibres, transmembrane currents can only occur at the nodes of Ranvier where the axonal membrane is exposed, so the excitation of the axonal membrane jumps from node to node. This propagation is called saltatory conduction and this movement of depolarization wave is much faster than in unmyelinated fibres.</span>

What happens in the G2 phase of the cell cycle?
balu736 [363]
The Best Answer :
 <span>"G2 phase is the third, final, and usually the shortest subphase during interphase within the cell cycle in which the cell undergoes a period of rapid growth to prepare for mitosis. It follows successful completion of DNA synthesis and chromosomal replication during the S phase, and occurs during a period of often four to five hours. This far into interphase the nucleus is well defined, bound by a nuclear envelope and contains at least one nucleolus. Although chromosomes have been replicated they cannot yet be distinguished individually because they are still in the form of loosely packed chromatin fibers. The G2 phase prepares the cell for mitosis (M phase) which is initiated by prophase. 
At the end of this gap phase is a control checkpoint (G2 checkpoint) to determine if the cell can proceed to enter M phase and divide. The G2 checkpoint prevents cells from entering mitosis with DNA damaged since the last division, providing an opportunity for DNA repair and stopping the proliferation of damaged cells. Because the G2 checkpoint helps to maintain genomic stability, it is an important focus in understanding the molecular causes of cancer."</span>

AleksandrR [38]

Answer:

The correct answer is - water pollution.

Explanation:

In the US, water pollution is one of the most serious ecological problems, and sedimentation by filled with dirt, slit caused by development sites or construction sites. It is caused in the name of developing cities and states for new homes and other construction that is nothing but careless development that is causing water pollution in these areas including the Virginia.

The excessive silt has covered the spawning beds of fish causes spawning of the habitat. The dirt and slit and sediments cause inhibiting light to aquatic plants that result in less oxygen and food for aqautic life.
