In the body, the main protective layer is known as the epithelium, this can be found in the skin as well as other organs such as the lungs.
The body is often exposed to external factors that can damage it; due to this, throughout evolution, most animals and multicellular organisms have developed protective mechanisms.
In the case of humans and other animals, the protective layer is known as the epithelium, which is composed of epithelial cells. This protective layer can be found internally and externally.
External layer: This is the first protective layer, commonly known as skin, this layer protects the inner organs from extreme temperatures, changes in pressure, etc.
Internal layer: Organs such as the lungs or the ones in the gastrointestinal system are all covered by a thin epithelial layer that helps each organ to be protected.

The answer to this question B (10+10)/(5-3)
can be split into hydrogen and oxygen chemical property
is liquid at room temperature physical property
has a density of 1.0 g/cm³ physical property
reacts with certain metals chemical property
Explanation:
The physical properties of matter are the properties that occur when no change is occurring to a matter. They are usually observed with our senses or some simple laboratory experiments.
Some of the physical properties are boiling point, density, state of matter, e.t.c
The chemical properties are the properties that occurs when a matter undergoes some chemical changes.
For example rusting, decomposition, reactivity e.t.c
