Answer:
this is beacuse stars are always in the sky
Explanation:
stars are always in the sky they are in the sky we just cant see it through our naked eye.. Also, while those super-massive stars will die suddenly as supernovae, most stars experience much slower deaths taking hundreds of thousands or millions of years to play out. Examples of famous stars already in the act of dying include Arcturus and Aldebaran.
<h2>CNS </h2>
Explanation:
An example of a myelin producing cell in the CNS is oligodendrocyte
- The major function of oligodendrocytes is the formation of myelin
- Myelin acts as an insulator of axonal segments and is a prerequisite for the high velocity of nerve conduction
- Larger axons form thicker myelin
- During development, oligodendrocytes arise from precursors located in the sub-ventricular zone such as the sub-ventricular zone of the lateral ventricles for the cerebrum or the fourth ventricle for the cerebellum
- In the spinal cord, oligodendrocytes originate from the ventral regions of the neural tube and in the optic nerve they migrate into the nerve from the third ventricle
- It is the oligodendrocyte precursor cells which migrate to their destination where they then differentiate into the more mature oligodendrocytes
- The proliferation of the oligodendrocyte progenitor cells is controlled by a number of growth factors released predominantly from neurons but also from astrocytes such as platelet derived growth factor (PDGF) or fibroblast growth factor (FGF)
Get a goodnight rest to do that go to bed at a early time like 8:00 and keep tech out of bedroom
