One animal that has thick feathers is the ostrich. Ostriches have a double layer of feathers, with the outer layer being long, loose, and soft, while the inner layer is shorter and denser, providing insulation and protection.
Arthropod have exoskeleton. The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer.
thick layer
The thickness of Earth's layers varies: the crust is between 5-70 km thick, the mantle is about 2,900 km thick, the outer core is about 2,300 km thick, and the inner core is about 1,200 km thick.
The outer core is a liquid that is in between the inner core and mantle. It is 2,000km thick.
crust: average of 32 km thick mantle: 2900 km thick outer core: 2200 km thick inner core 1250 km thick
what is the inner layer of the mitochondria
inner layer? well, i guess you could call the organs and the organ tissue as the inner layer.
