Lithosphere
13 major plates
Asthenosphere
Explanation:
The surface or lithosphere of the earth is broken into about 7 major plates that floats on the liquid asthenosphere.
The analogy above describes the theory behind plate tectonics.
- The crust and the rigid part of the upper mantle forms the lithosphere.
- The lithosphere is broken down into series of pieces called plates.
- There about 13 plates on earth surface.
- The rigid plates moves on the weak asthenosphere below as a result of convection currents.

Answer:
Conditions in the body must be constantly controlled because cells depend on the body's environment to live and function. The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly.

Calcium is one substance that is secreted elsewhere but not in the proximal convoluted tubule.
<h3>Renal reabsorption and secretion</h3>
Renal reabsorption is defined as the movement of water and specific solutes from the renal tubule back into the plasma.
Renal secretion is defined as the process by which waste ions and hydrogen ions pass from the renal capillaries into the renal tubule to be excreted into the urine.
At the proximal convoluted tubule, calcium is reabsorbed but not secreted. Therefore, Calcium is one substance that is secreted elsewhere but not in the proximal convoluted tubule.

The reasons why a rancher may plant several varieties of grass for grazing on the same ranch are for making hay where some horse owners may prefer to feed their animals with a feeding mixture of alfafa hay and timothy hay. Secondly, they plant the grasses for grazing their animals since the grasses may be having different soil conditions in different fields. lastly, the farmers may be raising different animals with varying nutritional needs.
