It also functions to retain body fluids, eliminate waste products and regulate body temperature.
The integumentary system works with all the other systems of the body to maintain internal conditions of the body needed for proper functioning.
Answer:
(a) Flippase
Explanation:
The flippases are the transbilayer translocators present in the plasma membrane and are one of the proteins that are responsible for the asymmetric nature of the plasma membrane with respect to the distribution of phospholipids.
The flippases are the P-type ATPase that serves to move the phosphatidylethanolamine and phosphatidylserine from the outer to the cytosolic leaflet of the plasma membrane.
These proteins are responsible for the abundance of phosphatidylethanolamine and phosphatidylserine in the cytosolic leaflet and that of the sphingolipids and phosphatidylcholine in the outer leaflet.
Correct answer: A). Plates
The tectonic plates are the pieces of earth's crust and mantle, which is together referred to as the lithosphere. The lithosphere is a rigid outermost layer of the planet that is broken down into the tectonic plates.
The plates move because the earth's lithosphere has a higher strength than the asthenosphere. During an earthquake, the plates move over each other.
Hence, the correct answer would be option A.
