The lipids are arranged in the membrane with the polar heads towards the inner side

In observing opithelial cells under a microscope the cells are arranged in a single layer and look tall, narrow and the nucleus is located close to the basal side of the cell. The specimen is what type of epithelial tissue ?

Which type of lipid is found in cell membrane?

In Young's double slit experiment, slits are arranged in such a way that besides central bright fringes, there is only one bright fringe on either side of it. Slit separation d for the given condition cannot be (if lamda is wavelength of the light used):

The cell membrane is composed to lipids that are arranged in

The lipids component of cell membrane mainly consists of

Six identical coins are arranged in a row. The total number of ways in which the number of heads is equal to the number of tails is

How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it in the same way? If not, then how are these transported across the membrane?
