<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)
Answer:
c
Explanation:
because if you look at Darwin's change of evolution finches like these can break walnuts and pick at it because they have strong beaks
<span>Hydrogenous sediments originate from elements in seawater. </span><span>Hydrogenous sediments are formed by precipitation of minerals from the ocean’s water or can be formed as a new mineral as a result of chemical reactions between the water of the ocean and sediments that already exist on the ocean floor. </span>
Once starch in a person's diet has been broken down into monosaccharides those subunits are absorbed in the small intestines
Carbohydrates, also referred to as sugars, are a type of polymer. They are polymers whose subunits are linked together by glycosidic linkages that, when water is released, form a bond between two monomeric units. The amount of monomers that must come together to make a carbohydrate allows for the division of the carbohydrates into various groups. The monosaccharide, commonly known as simple sugars, is the most basic type of carbohydrate chain.
Since they exist as a single unit and are not connected to any other monosaccharides, these molecules are frequently referred to as the monomers of a carbohydrate chain.

Answer:
The correct answer is- norepinephrine.
Explanation:
Norepinephrine is a hormone and also a neurotransmitter which is released from the adrenal medulla and with epinephrine it helps in generating the fight and flight response during the stress condition. Norepinephrine is synthesized from dopamine.
Cocaine binds to the structures which are known to regulate dopamine thereby it enhance the activity neurotransmitter norepinephrine which results in producing extreme alertness and exaggerated awareness and prepares our body for the stressful condition.
