The molten iron and nickel in the core of the Earth contribute to Thermal Energy.
asambeis [7]4 years ago
3 0

Answer: Earth's core is comprised of nickel and iron, and is divided into two types namely the outer core and the inner core. The outer core is liquid in nature whereas the inner core is solid in nature.

Due to the presence of heavy metals, the core of the earth radiates a huge amount of energy towards the surface, that drives the lithospheric plate to move over the mantle. This energy is the main source of plate tectonic movement.

What is medulla oblongata ?

  • Medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem.
  • The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.
  • The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration
  • The medulla is divided into two main parts: the ventral medulla (the frontal portion) and the dorsal medulla (the rear portion; also known as the tegmentum).
  • The ventral medulla contains a pair of triangular structures called pyramids, within which lie the pyramidal tracts.
  • The pyramidal tracts are made up of the corticospinal tract (running from the cerebral cortex to the spinal cord) and the corticobulbar tract (running from the motor cortex of the frontal lobe to the cranial nerves in the brainstem)

Answer:

Macromolecule OR nucleic acid

Explanation:

It is one of four main types of macromolecules found in all forms of life, and its full name is deoxyribonucleic acid.

Best bet is macromolecule, but this is a very vague question so nucleic acid could also be correct.
