What are the latest developments on research on Earth’s internal structure.

The internal structure of the earth is like a steel ball that has been inserted into the middle of a rubber ball that has then been rolled around in the mud which sticks to it.

Explanation:

The mud sticking unevenly on the outside of the ball represents the earth's crust. The rubber ball represents the mantle below the crust, and the steel ball inside is the earth's core. These are the basic layers.

Inside the earth, the mantle itself consists of an upper mantle and a lower mantel, and the iron consists of an outer core and inner core. The separations occur where the state of the substance changes. For the iron , the outer core is closer to a liquid, while the inner core is closer to a solid. Both are intensely hot.

If you need a 3-D representation of the internal structure of the earth, cut a spherically shaped avocado in half, and keep the half with the seed or pit. The pit is the core, the fruit is the mantel and the skin is the earth's crust. You can add in the other divisions as necessary.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
