Explanation:
The Nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from gas and dust orbiting the Sun. The theory was developed by Immanuel Kant and published in his Allgemeine Naturgeschichte und Theorie des Himmels ("Universal Natural History and Theory of the Heavens"), published in 1755 and then modified in 1796 by Pierre Laplace.
The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas. It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula.

Cell membrane is a structure of a cell that contains lipid bilayer and embedded proteins. It functions to protect the cell from the surroundings and also controls the materials entering in or leaving out of the cell. The red blood cells (erythrocytes) are cells of the blood that carry oxygen to be distributed to all the body tissues. The cell membrane of the red blood cells like many other body cells contain very few sodium channels.
