Answer: A(secondary active transport)
Explanation:
Secondary active transport, is transport of molecules across the cell membrane which utilizes energy created by co-transporter pumping of ions across the membrane in an electrochemical gradient.
The reabsorption of glucose from the proximal tubule occurs via secondary active transport.
The reabsorbption of glucose does not depend the concentration gradient but on the reabsorption of sodium a co-transporter.
ATP is used in the movements of Na+/K+. Energy is also produced from sodium electrochemical gradient concentration and it is enough energy to transport glucose across the membrane into the epithelial cells.

(several thousand acres of closely spaced colonies) can support and sustain a ... to 60 hectares of prairie dog colony is needed to support one Black-footed Ferret, ...
Explanation:
Answer
Lower Mantle-under high pressure and nearly solid.
Lithosphere-contains the crust
Core-creates the Earth’s magnetic field
Asthenosphere-most deformable layer.
Explanation
The mantle is located below the crust and it occupies the largest volume of the Earth’s volume. The mantle behaves like a plastic and at high pressures and temperatures the rocks in the mantle deform
The lithosphere is the outer shell that contains the crust and upper mantle. The lithosphere is divided into the oceanic layer and the continental layer. It is bounded by the atmosphere and the Asthenosphere.
