Answer: Venus, Mercury and Mars are the differentiated planets.
Planetary differentiation can be defined as the process by which the separation of different types of constituents takes place. They are differentiated on the basis of their chemical or physical behavior.The denser material of the planets sink to the center of the planet and the less denser particles rise at the surface of the planet.
Protease refers to a group of enzymes whose catalytic function is to hydrolyze peptide bonds of proteins. They are also called proteolytic enzymes or proteinases.
The lipid bilayer<span> has been firmly established as the universal basis for cell-</span>membrane<span> structure. It is easily seen by </span>electron<span> microscopy, although specialized techniques, such as x-ray diffraction and </span>freeze-fracture electron microscopy<span>, are needed to reveal the details of its organization. The bilayer structure is attributable to the special properties of the </span>lipid<span> molecules, which cause them to assemble spontaneously into bilayers even under simple artificial conditions</span>
