The answers are a, igneous, and b, sedimentary. Hope this helped!
Explanation:
As tectonic plates drift due to the convection currents of the mantle below, so does the climate on the tectonic plates. This is because the drift causes the continents to glide across latitudes. Different latitudes have different climatic conditions associated with them. An example is an equatorial climate in the equator, the subtropical climate in the mid-latitudes and polar climate in the polar region.
Therefore, even though this drift is happening very slowly over millions of years, the plant and animal species in these continental also slowly adapt to the changing climatic condition in their environment associated with these continental drifts.
<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:
first option: the measure of the average kinetic energy of particles in an object due to motion
Explanation:
when temperature increases, the motion of the particles also increase.
