The OSI (Open Systems Interconnect) 7-layer model describes all of computing and communication. The layers range from the physical wire, at the lowest layer, layer 1, up through applications (apps) at the highest layer, layer 7. Each higher layer uses each lower layer for computing and communication purposes. But who uses applications? Humans. So the human layer is the unspoken 8th, highest, layer of the model.
Yes the lower eqidermal layer is corvered with cuticle.
the lower layer
The layer that reflects radio waves of low frequency is the ionosphere layer known as the D-layer, which is located at an altitude of approximately 50-90 kilometers. Radio waves of low frequency, such as medium frequency (MF) and lower high frequency (HF), bounce off this layer for long-distance communication.
The energy is stored within the layer of iridium in the lower hemisphere of Antarctica. Oops i mean the lower hemisphere of the anaredia layer of glucose.
To observe the lower layer of a sample using a microscope, you should adjust the focus by turning the fine adjustment knob slowly to bring the lower layer into view. This will help bring the sample into sharper focus so you can see details on the lower layer more clearly.
upper layer
the less dense layer is on top and the more dense layer is below.
