Which of the statement about cell membrane is not true? * It contains protein molecules embedded in the lipid bilayer B. It is a differentially permeable membrane. C. It contains charged pores thus ions being O charged particles cross cell membrane much easier than neutral particles. D. It may get infolded to engulf solid or liquid material.
The physical characteristics of a cell influence how it functions. For example, the surface area and volume of a cell affect how efficiently waste is removed from the cell via diffusion. The table below shows data for four different cuboidal cells. Cuboidal cell Side length (um) Cell A 1 Cell B Cell C Cell D Surface area of a cube: A = 6s2 Volume of a cube: V = s3 Using the information from the table, what is the surface-area-to-volume ratio for the cuboidal cell that removes waste via diffusion most efficiently? -1 um 2. 4.

The solution has a lesser concentration of solutes and fluid will leave the cell. C. The solution has a greater concentration of solutes and fluid will move into the cell. D. The solution has a lesser concentration of solutes and fluid will move into the cell.
Which of the following provides the most likely explanation for the limiting factor of a cell's size? A B с D As the cell size increases, its volume increases while its surface area does not. As the cell size increases, its volume increases at a faster rate than its surface area. As the cell size increases, its volume increases at a slower rate than its surface area. As the cell size increases, its surface area increases while its volume does not.
