Answer:
The CORRECT ANSWER IS B.
B. Unlike the other countercurrent systems, a countercurrent multiplier system expends energy in active transport.
Explanation:
The countercurrent multiplier system involving the loop of Henle uses up energy in the form of ATP to actively conduct NaCl out of the filtrate in the upper region of the ascending limb of the loop. This energy in the form of ATP that is being used uniquely differentiates a countercurrent multiplier system from the different forms of countercurrent systems.
Epithelial tissue is composed of the innervated and avascular layer of cells which are tightly packed. It forms the outermost layer of the body and protects the internal layers and organs.
This tissue can be classified into different categories based on the shape of its cell, and the total number of the layers.
The epithelial tissue with only one layers is known as the simple epithelial tissue.
The epithelial cells that are thin, flat, and scaly are known as the squamous cells.
While the cubodial cells are round or square in shape.
Hence, the given blanks can be filled with classified, simple, squamous, and square.
