Answer:
The correct answer is B) Gregor Mendel.
Explanation:
Gregor Johann Mendel was an 18th-century Genetic Scientist whose works, although revolutionary, didn't come to scientific limelight until the 20th century.
He was famous for his experiment with the Pea Plant. Through his experiments, he brought to record many of the rules of heredity also called the laws Mendelian inheritance.
Mendel died in 1884 aged 61, however, his work serves as the foundation for modern-day genetic science.

Answer:
1. La enseñanza de la ciencia es importante porque: Contribuye a la formación del pensamiento lógico a través de la resolución de problemas concretos. Mejora la calidad de vida. Prepara para la futura inserción en el mundo científico – tecnológico
2. Las ciencias naturales buscan entender el funcionamiento del universo y el mundo que nos rodea. Se pueden distinguir cinco ramas principales: Física, Química, Astronomía, Geología y Biología.
3. Ramas, Historia, Sistematicidad, Experimentación, y Naturaleza
4. Existen dos categorías en que se agrupan las ciencias naturales, ciencias físicas y ciencias biológicas
5. Cuatro ciencias auxiliares de la Historia. Historiografía se trata de una disciplina que investiga el modo en que se construye la Historia oficial. Arte se una disciplina por completo autónoma, que centra su interés en las diversas formas de manifestación. Paleontología la ciencia que estudia a los fósiles de los seres orgánicos que habitaron nuestro mundo en épocas pasadas. Cartografía una rama de la geografía, interesada en los métodos de representación espacial del planeta
Explanation:
<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)
