shell structure
Graphite has delocalised electrons. It has layer structure (each layer is called graphene). The bonding of the carbons in the layer can be described as sp2 as the bond angles are 120 0. Each C atom has a p orbital perpendicular to the layer that contains a single electron. These p orbitals form pi bonds which spread across the layer.
The layer of Earth with the greatest amount of decayed material is the topmost layer, known as the soil layer or the humus layer. This layer contains organic matter formed from the decomposition of plants and animals, contributing to soil fertility.
Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice structure. Carbon atoms in graphene are bonded together in a single layer, making it an example of a two-dimensional material with unique properties due to its hexagonal arrangement.

shell structure
The prostate is encased in a layer called the capsule (which is tough muscle-like material) and this is part of the prostate, so it is not a separate structure.

The outer layer of a prokaryote cell is called the cell wall. It provides structure and protection to the cell, and is typically made of a rigid material like peptidoglycan.
There are 4 different layers that the Earth is composed of. The layer that has the melted material is the core layer. The core layer is also the hottest layer.
A bioprinter is any device which performs bioprinting - the construction of a biological structure by computer-aided, automatic, layer-by-layer deposition, transfer and patterning of small amounts of biological material.

The top layer of soil, called the O horizon or organic layer, contains humus. Humus is a dark, organic material that forms as plant and animal matter decomposes. It is rich in nutrients and helps improve soil structure and fertility.
The layer just below Earth's crust is the mantle. It is the thickest layer, and is composed of flowing rock material. The solid upper part of the mantle joins with the crust to form the lithosphere

Each C atom has a p orbital perpendicular to the layer that contains a single electron. These p orbitals form pi bonds which spread across the layer.
The third layer of soil structure, known as the C horizon, typically consists of partially weathered parent material. This layer is where the weathered rock fragments accumulate, and it contains less organic matter and nutrients compared to the top layers. The C horizon is usually denser and harder due to the presence of relatively unaltered materials.
